+
+## Installation
+
+To get started with PR-Agent quickly, you first need to acquire two tokens:
+
+1. An OpenAI key from [here](https://platform.openai.com/), with access to GPT-4.
+2. A GitHub\GitLab\BitBucket personal access token (classic) with the repo scope.
+
+There are several ways to use PR-Agent:
+
+**Locally**
+- [Using Docker image (no installation required)](INSTALL.md#use-docker-image-no-installation-required)
+- [Run from source](INSTALL.md#run-from-source)
+
+**GitHub specific methods**
+- [Run as a GitHub Action](INSTALL.md#run-as-a-github-action)
+- [Run as a polling server](INSTALL.md#run-as-a-polling-server)
+- [Run as a GitHub App](INSTALL.md#run-as-a-github-app)
+- [Deploy as a Lambda Function](INSTALL.md#deploy-as-a-lambda-function)
+- [AWS CodeCommit](INSTALL.md#aws-codecommit-setup)
+
+**GitLab specific methods**
+- [Run a GitLab webhook server](INSTALL.md#run-a-gitlab-webhook-server)
+
+**BitBucket specific methods**
+- [Run as a Bitbucket Pipeline](INSTALL.md#run-as-a-bitbucket-pipeline)
+- [Run on a hosted app](INSTALL.md#run-on-a-hosted-bitbucket-app)
+---
+
+### Use Docker image (no installation required)
+
+To request a review for a PR, or ask a question about a PR, you can run directly from the Docker image. Here's how:
+
+For GitHub:
+```
+docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
+```
+For GitLab:
+```
+docker run --rm -it -e OPENAI.KEY=<your key> -e CONFIG.GIT_PROVIDER=gitlab -e GITLAB.PERSONAL_ACCESS_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
+```
+For BitBucket:
+```
+docker run --rm -it -e CONFIG.GIT_PROVIDER=bitbucket -e OPENAI.KEY=$OPENAI_API_KEY -e BITBUCKET.BEARER_TOKEN=$BITBUCKET_BEARER_TOKEN codiumai/pr-agent:latest --pr_url=<pr_url> review
+```
+
+For other git providers, update CONFIG.GIT_PROVIDER accordingly, and check the `pr_agent/settings/.secrets_template.toml` file for the environment variables expected names and values.
+
+
+Similarly, to ask a question about a PR, run the following command:
+```
+docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent --pr_url <pr_url> ask "<your question>"
+```
+
+A list of the relevant tools can be found in the [tools guide](./docs/TOOLS_GUIDE.md).
+
+
+Note: If you want to ensure you're running a specific version of the Docker image, consider using the image's digest:
+```bash
+docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent@sha256:71b5ee15df59c745d352d84752d01561ba64b6d51327f97d46152f0c58a5f678 --pr_url <pr_url> review
+```
+in addition, you can run a [specific released versions](./RELEASE_NOTES.md) of pr-agent, for example:
+```
+codiumai/pr-agent@v0.8
+```
+
+---
+
+### Run from source
+
+1. Clone this repository:
+
+```
+git clone https://github.com/Codium-ai/pr-agent.git
+```
+
+2. Install the requirements in your favorite virtual environment:
+
+```
+pip install -r requirements.txt
+```
+
+3. Copy the secrets template file and fill in your OpenAI key and your GitHub user token:
+
+```
+cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
+chmod 600 pr_agent/settings/.secrets.toml
+# Edit .secrets.toml file
+```
+
+4. Add the pr_agent folder to your PYTHONPATH, then run the cli.py script:
+
+```
+export PYTHONPATH=[$PYTHONPATH:]<PATH to pr_agent folder>
+python3 -m pr_agent.cli --pr_url <pr_url> review
+python3 -m pr_agent.cli --pr_url <pr_url> ask <your question>
+python3 -m pr_agent.cli --pr_url <pr_url> describe
+python3 -m pr_agent.cli --pr_url <pr_url> improve
+python3 -m pr_agent.cli --pr_url <pr_url> add_docs
+python3 -m pr_agent.cli --issue_url <issue_url> similar_issue
+...
+```
+
+---
+
+### Run as a GitHub Action
+
+You can use our pre-built Github Action Docker image to run PR-Agent as a Github Action.
+
+1. Add the following file to your repository under `.github/workflows/pr_agent.yml`:
+
+```yaml
+on:
+  pull_request:
+  issue_comment:
+jobs:
+  pr_agent_job:
+    runs-on: ubuntu-latest
+    permissions:
+      issues: write
+      pull-requests: write
+      contents: write
+    name: Run pr agent on every pull request, respond to user comments
+    steps:
+      - name: PR Agent action step
+        id: pragent
+        uses: Codium-ai/pr-agent@main
+        env:
+          OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+** if you want to pin your action to a specific release (v0.7 for example) for stability reasons, use:
+```yaml
+on:
+  pull_request:
+  issue_comment:
+
+jobs:
+  pr_agent_job:
+    runs-on: ubuntu-latest
+    permissions:
+      issues: write
+      pull-requests: write
+      contents: write
+    name: Run pr agent on every pull request, respond to user comments
+    steps:
+      - name: PR Agent action step
+        id: pragent
+        uses: Codium-ai/pr-agent@v0.7
+        env:
+          OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+2. Add the following secret to your repository under `Settings > Secrets`:
+
+```
+OPENAI_KEY: <your key>
+```
+
+The GITHUB_TOKEN secret is automatically created by GitHub.
+
+3. Merge this change to your main branch.
+When you open your next PR, you should see a comment from `github-actions` bot with a review of your PR, and instructions on how to use the rest of the tools.
+
+4. You may configure PR-Agent by adding environment variables under the env section corresponding to any configurable property in the [configuration](pr_agent/settings/configuration.toml) file. Some examples:
+```yaml
+      env:
+        # ... previous environment values
+        OPENAI.ORG: "<Your organization name under your OpenAI account>"
+        PR_REVIEWER.REQUIRE_TESTS_REVIEW: "false" # Disable tests review
+        PR_CODE_SUGGESTIONS.NUM_CODE_SUGGESTIONS: 6 # Increase number of code suggestions
+```
+
+---
+
+### Run as a polling server
+Request reviews by tagging your GitHub user on a PR
+
+Follow [steps 1-3](#run-as-a-github-action) of the GitHub Action setup.
+
+Run the following command to start the server:
+
+```
+python pr_agent/servers/github_polling.py
+```
+
+---
+
+### Run as a GitHub App
+Allowing you to automate the review process on your private or public repositories.
+
+1. Create a GitHub App from the [Github Developer Portal](https://docs.github.com/en/developers/apps/creating-a-github-app).
+
+   - Set the following permissions:
+     - Pull requests: Read & write
+     - Issue comment: Read & write
+     - Metadata: Read-only
+     - Contents: Read-only
+   - Set the following events:
+     - Issue comment
+     - Pull request
+
+2. Generate a random secret for your app, and save it for later. For example, you can use:
+
+```
+WEBHOOK_SECRET=$(python -c "import secrets; print(secrets.token_hex(10))")
+```
+
+3. Acquire the following pieces of information from your app's settings page:
+
+   - App private key (click "Generate a private key" and save the file)
+   - App ID
+
+4. Clone this repository:
+
+```
+git clone https://github.com/Codium-ai/pr-agent.git
+```
+
+5. Copy the secrets template file and fill in the following:
+    ```
+    cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
+    # Edit .secrets.toml file
+    ```
+   - Your OpenAI key.
+   - Copy your app's private key to the private_key field.
+   - Copy your app's ID to the app_id field.
+   - Copy your app's webhook secret to the webhook_secret field.
+   - Set deployment_type to 'app' in [configuration.toml](./pr_agent/settings/configuration.toml)
+
+> The .secrets.toml file is not copied to the Docker image by default, and is only used for local development.
+> If you want to use the .secrets.toml file in your Docker image, you can add remove it from the .dockerignore file.
+> In most production environments, you would inject the secrets file as environment variables or as mounted volumes.
+> For example, in order to inject a secrets file as a volume in a Kubernetes environment you can update your pod spec to include the following,
+> assuming you have a secret named `pr-agent-settings` with a key named `.secrets.toml`:
+```
+       volumes:
+        - name: settings-volume
+          secret:
+            secretName: pr-agent-settings
+// ...
+       containers:
+// ...
+          volumeMounts:
+            - mountPath: /app/pr_agent/settings_prod
+              name: settings-volume
+```
+
+> Another option is to set the secrets as environment variables in your deployment environment, for example `OPENAI.KEY` and `GITHUB.USER_TOKEN`.
+
+6. Build a Docker image for the app and optionally push it to a Docker repository. We'll use Dockerhub as an example:
+
+```
+docker build . -t codiumai/pr-agent:github_app --target github_app -f docker/Dockerfile
+docker push codiumai/pr-agent:github_app  # Push to your Docker repository
+```
+
+7. Host the app using a server, serverless function, or container environment. Alternatively, for development and
+   debugging, you may use tools like smee.io to forward webhooks to your local machine.
+    You can check [Deploy as a Lambda Function](#deploy-as-a-lambda-function)
+
+8. Go back to your app's settings, and set the following:
+
+   - Webhook URL: The URL of your app's server or the URL of the smee.io channel.
+   - Webhook secret: The secret you generated earlier.
+
+9. Install the app by navigating to the "Install App" tab and selecting your desired repositories.
+
+> **Note:** When running PR-Agent from GitHub App, the default configuration file (configuration.toml) will be loaded.<br>
+> However, you can override the default tool parameters by uploading a local configuration file `.pr_agent.toml`<br>
+> For more information please check out the [USAGE GUIDE](./Usage.md#working-with-github-app)
+---
+
+### Deploy as a Lambda Function
+
+1. Follow steps 1-5 of [Method 5](#run-as-a-github-app).
+2. Build a docker image that can be used as a lambda function
+    ```shell
+    docker buildx build --platform=linux/amd64 . -t codiumai/pr-agent:serverless -f docker/Dockerfile.lambda
+   ```
+3. Push image to ECR
+    ```shell
+	docker tag codiumai/pr-agent:serverless <AWS_ACCOUNT>.dkr.ecr.<AWS_REGION>.amazonaws.com/codiumai/pr-agent:serverless
+	docker push <AWS_ACCOUNT>.dkr.ecr.<AWS_REGION>.amazonaws.com/codiumai/pr-agent:serverless
+    ```
+4. Create a lambda function that uses the uploaded image. Set the lambda timeout to be at least 3m.
+5. Configure the lambda function to have a Function URL.
+6. Go back to steps 8-9 of [Method 5](#run-as-a-github-app) with the function url as your Webhook URL.
+    The Webhook URL would look like `https://<LAMBDA_FUNCTION_URL>/api/v1/github_webhooks`
+
+---
+
+### AWS CodeCommit Setup
+
+Not all features have been added to CodeCommit yet.  As of right now, CodeCommit has been implemented to run the pr-agent CLI on the command line, using AWS credentials stored in environment variables.  (More features will be added in the future.)  The following is a set of instructions to have pr-agent do a review of your CodeCommit pull request from the command line:
+
+1. Create an IAM user that you will use to read CodeCommit pull requests and post comments
+    * Note: That user should have CLI access only, not Console access
+2. Add IAM permissions to that user, to allow access to CodeCommit (see IAM Role example below)
+3. Generate an Access Key for your IAM user
+4. Set the Access Key and Secret using environment variables (see Access Key example below)
+5. Set the `git_provider` value to `codecommit` in the `pr_agent/settings/configuration.toml` settings file
+6. Set the `PYTHONPATH` to include your `pr-agent` project directory
+    * Option A: Add `PYTHONPATH="/PATH/TO/PROJECTS/pr-agent` to your `.env` file
+    * Option B: Set `PYTHONPATH` and run the CLI in one command, for example:
+        * `PYTHONPATH="/PATH/TO/PROJECTS/pr-agent python pr_agent/cli.py [--ARGS]`
+
+##### AWS CodeCommit IAM Role Example
+
+Example IAM permissions to that user to allow access to CodeCommit:
+
+* Note: The following is a working example of IAM permissions that has read access to the repositories and write access to allow posting comments
+* Note: If you only want pr-agent to review your pull requests, you can tighten the IAM permissions further, however this IAM example will work, and allow the pr-agent to post comments to the PR
+* Note: You may want to replace the `"Resource": "*"` with your list of repos, to limit access to only those repos
+
+```
+{
+    "Version": "2012-10-17",
+    "Statement": [
+        {
+            "Effect": "Allow",
+            "Action": [
+                "codecommit:BatchDescribe*",
+                "codecommit:BatchGet*",
+                "codecommit:Describe*",
+                "codecommit:EvaluatePullRequestApprovalRules",
+                "codecommit:Get*",
+                "codecommit:List*",
+                "codecommit:PostComment*",
+                "codecommit:PutCommentReaction",
+                "codecommit:UpdatePullRequestDescription",
+                "codecommit:UpdatePullRequestTitle"
+            ],
+            "Resource": "*"
+        }
+    ]
+}
+```
+
+##### AWS CodeCommit Access Key and Secret
+
+Example setting the Access Key and Secret using environment variables
+
+```sh
+export AWS_ACCESS_KEY_ID="XXXXXXXXXXXXXXXX"
+export AWS_SECRET_ACCESS_KEY="XXXXXXXXXXXXXXXX"
+export AWS_DEFAULT_REGION="us-east-1"
+```
+
+##### AWS CodeCommit CLI Example
+
+After you set up AWS CodeCommit using the instructions above, here is an example CLI run that tells pr-agent to **review** a given pull request.
+(Replace your specific PYTHONPATH and PR URL in the example)
+
+```sh
+PYTHONPATH="/PATH/TO/PROJECTS/pr-agent" python pr_agent/cli.py \
+  --pr_url https://us-east-1.console.aws.amazon.com/codesuite/codecommit/repositories/MY_REPO_NAME/pull-requests/321 \
+  review
+```
+
+---
+
+### Run a GitLab webhook server
+
+1. From the GitLab workspace or group, create an access token. Enable the "api" scope only.
+2. Generate a random secret for your app, and save it for later. For example, you can use:
+
+```
+WEBHOOK_SECRET=$(python -c "import secrets; print(secrets.token_hex(10))")
+```
+3. Follow the instructions to build the Docker image, setup a secrets file and deploy on your own server from [Method 5](#run-as-a-github-app) steps 4-7.
+4. In the secrets file, fill in the following:
+    - Your OpenAI key.
+    - In the [gitlab] section, fill in personal_access_token and shared_secret. The access token can be a personal access token, or a group or project access token.
+    - Set deployment_type to 'gitlab' in [configuration.toml](./pr_agent/settings/configuration.toml)
+5. Create a webhook in GitLab. Set the URL to the URL of your app's server. Set the secret token to the generated secret from step 2.
+In the "Trigger" section, check the ‘comments’ and ‘merge request events’ boxes.
+6. Test your installation by opening a merge request or commenting or a merge request using one of CodiumAI's commands.
+
+
+
+### Run as a Bitbucket Pipeline
+
+
+You can use the Bitbucket Pipeline system to run PR-Agent on every pull request open or update.
+
+1. Add the following file in your repository bitbucket_pipelines.yml
+
+```yaml
+pipelines:
+    pull-requests:
+      '**':
+        - step:
+            name: PR Agent Review
+            image: python:3.10
+            services:
+              - docker
+            script:
+              - docker run -e CONFIG.GIT_PROVIDER=bitbucket -e OPENAI.KEY=$OPENAI_API_KEY -e BITBUCKET.BEARER_TOKEN=$BITBUCKET_BEARER_TOKEN codiumai/pr-agent:latest --pr_url=https://bitbucket.org/$BITBUCKET_WORKSPACE/$BITBUCKET_REPO_SLUG/pull-requests/$BITBUCKET_PR_ID review
+```
+
+2. Add the following secure variables to your repository under Repository settings > Pipelines > Repository variables.
+OPENAI_API_KEY: <your key>
+BITBUCKET_BEARER_TOKEN: <your token>
+
+You can get a Bitbucket token for your repository by following Repository Settings -> Security -> Access Tokens.
+
+
+### Run on a hosted Bitbucket app
+
+Please contact <support@codium.ai> if you're interested in a hosted BitBucket app solution that provides full functionality including PR reviews and comment handling. It's based on the [bitbucket_app.py](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/git_providers/bitbucket_provider.py) implmentation.

 We prioritize additions over deletions:

+## Installation
 
-
-## Quickstart
-
-To get started with pr-agent quickly, you first need to acquire two tokens:
+To get started with PR-Agent quickly, you first need to acquire two tokens:
 
 1. An OpenAI key from [here](https://platform.openai.com/), with access to GPT-4.
 2. A GitHub personal access token (classic) with the repo scope.
 
-There are several ways to use pr-agent. Let's start with the simplest one:
-
----
-
-#### Method 1: Use Docker image (no installation required)
-
-To request a review for a PR, or ask a question about a PR, you can run directly from the Docker image. Here's how:
-
-1. To request a review for a PR, run the following command:
-
-```
-docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent --pr_url <pr url>
-```
-
-2. To ask a question about a PR, run the following command:
-
-```
-docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent --pr_url <pr url> --question "<your question>"
-```
-
-Possible questions you can ask include:
-
-- What is the main theme of this PR?
-- Is the PR ready for merge?
-- What are the main changes in this PR?
-- Should this PR be split into smaller parts?
-- Can you compose a rhymed song about this PR.
-
----
-
-#### Method 2: Run from source
-
-1. Clone this repository:
-
-```
-git clone https://github.com/Codium-ai/pr-agent.git
-```
-
-2. Install the requirements in your favorite virtual environment:
-
-```
-pip install -r requirements.txt
-```
-
-3. Copy the secrets template file and fill in your OpenAI key and your GitHub user token:
-
-```
-cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
-# Edit .secrets.toml file
-```
-
-4. Run the appropriate Python scripts from the scripts folder:
-
-```
-python pr_agent/cli.py --pr_url <pr url>
-python pr_agent/cli.py --pr_url <pr url> --question "<your question>"
-```
-
----
-
-#### Method 3: Method 3: Run as a polling server; request reviews by tagging your Github user on a PR
-
-Follow steps 1-3 of method 2.
-Run the following command to start the server:
-
-```
-python pr_agent/servers/github_polling.py
-```
-
----
-
-#### Method 4: Run as a Github App, allowing you to automate the review process on your private or public repositories.
-
-1. Create a GitHub App from the [Github Developer Portal](https://docs.github.com/en/developers/apps/creating-a-github-app).
-
-   - Set the following permissions:
-     - Pull requests: Read & write
-     - Issue comment: Read & write
-     - Metadata: Read-only
-   - Set the following events:
-     - Issue comment
-     - Pull request
-
-2. Generate a random secret for your app, and save it for later. For example, you can use:
-
-```
-WEBHOOK_SECRET=$(python -c "import secrets; print(secrets.token_hex(10))")
-```
-
-3. Acquire the following pieces of information from your app's settings page:
-
-   - App private key (click "Generate a private key", and save the file)
-   - App ID
-
-4. Clone this repository:
-
-```
-git clone https://github.com/Codium-ai/pr-agent.git
-```
-
-5. Copy the secrets template file and fill in the following:
-   - Your OpenAI key.
-   - Set deployment_type to 'app'
-   - Copy your app's private key to the private_key field.
-   - Copy your app's ID to the app_id field.
-   - Copy your app's webhook secret to the webhook_secret field.
-
-```
-cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
-# Edit .secrets.toml file
-```
-
-6. Build a Docker image for the app and optionally push it to a Docker repository. We'll use Dockerhub as an example:
-
-```
-docker build . -t codiumai/pr-agent:github_app --target github_app -f docker/Dockerfile
-docker push codiumai/pr-agent:github_app  # Push to your Docker repository
-```
-
-7. Host the app using a server, serverless function, or container environment. Alternatively, for development and
-   debugging, you may use tools like smee.io to forward webhooks to your local machine.
-
-8. Go back to your app's settings, set the following:
-
-   - Webhook URL: The URL of your app's server, or the URL of the smee.io channel.
-   - Webhook secret: The secret you generated earlier.
-
-9. Install the app by navigating to the "Install App" tab, and selecting your desired repositories.

-## Usage and Tools
-
-CodiumAI pr-agent provides two types of interactions ("tools"): `"PR Reviewer"` and `"PR Q&A"`.
-
-- The "PR Reviewer" tool automatically analyzes PRs, and provides different types of feedbacks.
-- The "PR Q&A" tool answers free-text questions about the PR.
-
-### PR Reviewer
-
-Here is a quick overview of the different sub-tools of PR Reviewer:
-
-- PR Analysis
-  - Summarize main theme
-  - PR type classification
-  - Is the PR covered by relevant tests
-  - Is this a focused PR
-  - Are there security concerns
-- PR Feedback
-  - General PR suggestions
-  - Code suggestions
-
-This is how a typical output of the PR Reviewer looks like:
-
----
-
-#### PR Analysis
-
-- 🎯 **Main theme:** Adding language extension handler and token handler
-- 📌 **Type of PR:** Enhancement
-- 🧪 **Relevant tests added:** No
-- ✨ **Focused PR:** Yes, the PR is focused on adding two new handlers for language extension and token counting.
-- 🔒 **Security concerns:** No, the PR does not introduce possible security concerns or issues.
-
-#### PR Feedback
-
-- 💡 **General PR suggestions:** The PR is generally well-structured and the code is clean. However, it would be beneficial to add some tests to ensure the new handlers work as expected. Also, consider adding docstrings to the new functions and classes to improve code readability and maintainability.
-
-- 🤖 **Code suggestions:**
-
-  - **relevant file:** pr_agent/algo/language_handler.py
-
-    **suggestion content:** Consider using a set instead of a list for 'bad_extensions' as checking membership in a set is faster than in a list. [medium]
-
-  - **relevant file:** pr_agent/algo/language_handler.py
-
-    **suggestion content:** In the 'filter_bad_extensions' function, you are splitting the filename on '.' and taking the last element to get the extension. This might not work as expected if the filename contains multiple '.' characters. Consider using 'os.path.splitext' to get the file extension more reliably. [important]

-### PR Q&A
-
-This tool answers free-text questions about the PR. This is how a typical output of the PR Q&A looks like:
-
-**Question**: summarize for me the PR in 4 bullet points
-
-**Answer**:
-
-- The PR introduces a new feature to sort files by their main languages. It uses a mapping of programming languages to their file extensions to achieve this.
-- It also introduces a filter to exclude files with certain extensions, deemed as 'bad extensions', from the sorting process.
-- The PR modifies the `get_pr_diff` function in `pr_processing.py` to use the new sorting function. It also refactors the code to move the PR pruning logic into a separate function.
-- A new `TokenHandler` class is introduced in `token_handler.py` to handle token counting operations. This class is initialized with a PR, variables, system, and user, and provides methods to get system and user tokens and to count tokens in a patch.

 Check out the [PR Compression strategy](./PR_COMPRESSION.md) page for more details on how we convert a code diff to a manageable LLM prompt
 
+## Why use PR-Agent?
+
+A reasonable question that can be asked is: `"Why use PR-Agent? What make it stand out from existing tools?"`
+
+Here are some advantages of PR-Agent:
+
+- We emphasize **real-life practical usage**. Each tool (review, improve, ask, ...) has a single GPT-4 call, no more. We feel that this is critical for realistic team usage - obtaining an answer quickly (~30 seconds) and affordably.
+- Our [PR Compression strategy](./PR_COMPRESSION.md)  is a core ability that enables to effectively tackle both short and long PRs.
+- Our JSON prompting strategy enables to have **modular, customizable tools**. For example, the '/review' tool categories can be controlled via the [configuration](pr_agent/settings/configuration.toml) file. Adding additional categories is easy and accessible.
+- We support **multiple git providers** (GitHub, Gitlab, Bitbucket, CodeCommit), **multiple ways** to use the tool (CLI, GitHub Action, GitHub App, Docker, ...), and **multiple models** (GPT-4, GPT-3.5, Anthropic, Cohere, Llama2).
+- We are open-source, and welcome contributions from the community.
+
+
 ## Roadmap
 
-- [ ] Support open-source models, as a replacement for openai models. Note that a minimal requirement for each open-source model is to have 8k+ context, and good support for generating json as an output
-- [ ] Support other Git providers, such as Gitlab and Bitbucket.
-- [ ] Develop additional logics for handling large PRs, and compressing git patches
-- [ ] Dedicated tools and sub-tools for specific programming languages (Python, Javascript, Java, C++, etc)
+- [x] Support additional models, as a replacement for OpenAI (see [here](https://github.com/Codium-ai/pr-agent/pull/172))
+- [x] Develop additional logic for handling large PRs (see [here](https://github.com/Codium-ai/pr-agent/pull/229))
 - [ ] Add additional context to the prompt. For example, repo (or relevant files) summarization, with tools such a [ctags](https://github.com/universal-ctags/ctags)
+- [x] PR-Agent for issues
 - [ ] Adding more tools. Possible directions:
-  - [ ] Code Quality
-  - [ ] Coding Style
+  - [x] PR description
+  - [x] Inline code suggestions
+  - [x] Reflect and review
+  - [x] Rank the PR (see [here](https://github.com/Codium-ai/pr-agent/pull/89))   
+  - [ ] Enforcing CONTRIBUTING.md guidelines
   - [ ] Performance (are there any performance issues)
-  - [ ] Documentation (is the PR properly documented)
-  - [ ] Rank the PR importance
+  - [x] Documentation (is the PR properly documented)
   - [ ] ...
 
+See the [Release notes](./RELEASE_NOTES.md) for updates on the latest changes.

+
+### Introduction
+
+After [installation](/INSTALL.md), there are three basic ways to invoke CodiumAI PR-Agent:
+1. Locally running a CLI command
+2. Online usage - by [commenting](https://github.com/Codium-ai/pr-agent/pull/229#issuecomment-1695021901) on a PR
+3. Enabling PR-Agent tools to run automatically when a new PR is opened
+
+
+Specifically, CLI commands can be issued by invoking a pre-built [docker image](/INSTALL.md#running-from-source), or by invoking a [locally cloned repo](INSTALL.md#method-2-run-from-source).
+For online usage, you will need to setup either a [GitHub App](INSTALL.md#method-5-run-as-a-github-app), or a [GitHub Action](INSTALL.md#method-3-run-as-a-github-action).
+GitHub App and GitHub Action also enable to run PR-Agent specific tool automatically when a new PR is opened.
+
+
+#### The configuration file
+The different tools and sub-tools used by CodiumAI PR-Agent are adjustable via the **[configuration file](pr_agent/settings/configuration.toml)**.
+In addition to general configuration options, each tool has its own configurations. For example, the `review` tool will use parameters from the [pr_reviewer](/pr_agent/settings/configuration.toml#L16) section in the configuration file.
+
+The [Tools Guide](./docs/TOOLS_GUIDE.md) provides a detailed description of the different tools and their configurations.
+
+#### Ignoring files from analysis
+In some cases, you may want to exclude specific files or directories from the analysis performed by CodiumAI PR-Agent. This can be useful, for example, when you have files that are generated automatically or files that shouldn't be reviewed, like vendored code.
+
+To ignore files or directories, edit the **[ignore.toml](/pr_agent/settings/ignore.toml)** configuration file. This setting is also exposed the following environment variables:
+
+ - `IGNORE.GLOB`
+ - `IGNORE.REGEX`
+
+See [dynaconf envvars documentation](https://www.dynaconf.com/envvars/).
+
+#### git provider
+The [git_provider](pr_agent/settings/configuration.toml#L4) field in the configuration file determines the GIT provider that will be used by PR-Agent. Currently, the following providers are supported:
+`
+"github", "gitlab", "azure", "codecommit", "local", "gerrit"
+`
+
+[//]: # (** online usage:**)
+
+[//]: # (Options that are available in the configuration file can be specified at run time when calling actions. Two examples:)
+
+[//]: # (```)
+
+[//]: # (- /review --pr_reviewer.extra_instructions="focus on the file: ...")
+
+[//]: # (- /describe --pr_description.add_original_user_description=false -pr_description.extra_instructions="make sure to mention: ...")
+
+[//]: # (```)
+
+### Working from a local repo (CLI)
+When running from your local repo (CLI), your local configuration file will be used.
+Examples for invoking the different tools via the CLI:
+
+- **Review**:       `python -m pr_agent.cli --pr_url=<pr_url>  review`
+- **Describe**:     `python -m pr_agent.cli --pr_url=<pr_url>  describe`
+- **Improve**:      `python -m pr_agent.cli --pr_url=<pr_url>  improve`
+- **Ask**:          `python -m pr_agent.cli --pr_url=<pr_url>  ask "Write me a poem about this PR"`
+- **Reflect**:      `python -m pr_agent.cli --pr_url=<pr_url>  reflect`
+- **Update Changelog**:      `python -m pr_agent.cli --pr_url=<pr_url>  update_changelog`
+
+`<pr_url>` is the url of the relevant PR (for example: https://github.com/Codium-ai/pr-agent/pull/50).
+
+**Notes:**
+
+(1) in addition to editing your local configuration file, you can also change any configuration value by adding it to the command line:
+```
+python -m pr_agent.cli --pr_url=<pr_url>  /review --pr_reviewer.extra_instructions="focus on the file: ..."
+```
+
+(2) You can print results locally, without publishing them, by setting in `configuration.toml`:
+```
+[config]
+publish_output=true
+verbosity_level=2
+```
+This is useful for debugging or experimenting with the different tools.
+
+
+### Online usage
+
+Online usage means invoking PR-Agent tools by [comments](https://github.com/Codium-ai/pr-agent/pull/229#issuecomment-1695021901) on a PR.
+Commands for invoking the different tools via comments:
+
+- **Review**:       `/review`
+- **Describe**:     `/describe`
+- **Improve**:      `/improve`
+- **Ask**:          `/ask "..."`
+- **Reflect**:      `/reflect`
+- **Update Changelog**:      `/update_changelog`
+
+
+To edit a specific configuration value, just add `--config_path=<value>` to any command.
+For example if you want to edit the `review` tool configurations, you can run:
+```
+/review --pr_reviewer.extra_instructions="..." --pr_reviewer.require_score_review=false
+```
+Any configuration value in [configuration file](pr_agent/settings/configuration.toml) file can be similarly edited. comment `/config` to see the list of available configurations.
+
+
+### Working with GitHub App
+When running PR-Agent from [GitHub App](INSTALL.md#method-5-run-as-a-github-app), the default configurations from a pre-built docker will be initially loaded.
+
+#### GitHub app automatic tools
+The [github_app](pr_agent/settings/configuration.toml#L56) section defines GitHub app specific configurations.  
+In this section you can define configurations to control the conditions for which tools will **run automatically**.  
+Note that a local `.pr_agent.toml` file enables you to edit and customize the default parameters of any tool, not just the ones that are run automatically.
+
+##### GitHub app automatic tools for PR actions
+The GitHub app can respond to the following actions on a PR:
+1. `opened` - Opening a new PR
+2. `reopened` - Reopening a closed PR
+3. `ready_for_review` - Moving a PR from Draft to Open
+4. `review_requested` - Specifically requesting review (in the PR reviewers list) from the `github-actions[bot]` user
+
+The configuration parameter `handle_pr_actions` defines the list of actions for which the GitHub app will trigger the PR-Agent.  
+The configuration parameter `pr_commands` defines the list of tools that will be **run automatically** when one of the above action happens (e.g. a new PR is opened):
+```
+[github_app]
+handle_pr_actions = ['opened', 'reopened', 'ready_for_review', 'review_requested']
+pr_commands = [
+    "/describe --pr_description.add_original_user_description=true --pr_description.keep_original_user_title=true",
+    "/auto_review",
+]
+```
+This means that when a new PR is opened/reopened or marked as ready for review, PR-Agent will run the `describe` and `auto_review` tools.  
+For the describe tool, the `add_original_user_description` and `keep_original_user_title` parameters will be set to true.
+
+You can override the default tool parameters by uploading a local configuration file called `.pr_agent.toml` to the root of your repo.
+For example, if your local `.pr_agent.toml` file contains:
+```
+[pr_description]
+add_original_user_description = false
+keep_original_user_title = false
+```
+When a new PR is opened, PR-Agent will run the `describe` tool with the above parameters.
+
+To cancel the automatic run of all the tools, set:
+```
+[github_app]
+handle_pr_actions = []
+```
+
+##### GitHub app automatic tools for new code (PR push)
+In addition the running automatic tools when a PR is opened, the GitHub app can also respond to new code that is pushed to an open PR.
+
+The configuration toggle `handle_push_trigger` can be used to enable this feature.  
+The configuration parameter `push_commands` defines the list of tools that will be **run automatically** when new code is pushed to the PR.
+```
+[github_app]
+handle_push_trigger = true
+push_commands = [
+    "/describe --pr_description.add_original_user_description=true --pr_description.keep_original_user_title=true",
+    "/auto_review -i --pr_reviewer.remove_previous_review_comment=true",
+]
+```
+The means that when new code is pused to the PR, the PR-Agent will run the `describe` and incremental `auto_review` tools.  
+For the describe tool, the `add_original_user_description` and `keep_original_user_title` parameters will be set to true.  
+For the `auto_review` tool, it will run in incremental mode, and the `remove_previous_review_comment` parameter will be set to true.
+
+Much like the configurations for `pr_commands`, you can override the default tool paramteres by uploading a local configuration file to the root of your repo.
+
+#### Editing the prompts
+The prompts for the various PR-Agent tools are defined in the `pr_agent/settings` folder.
+In practice, the prompts are loaded and stored as a standard setting object.
+Hence, editing them is similar to editing any other configuration value - just place the relevant key in `.pr_agent.toml`file, and override the default value.
+
+For example, if you want to edit the prompts of the [describe](./pr_agent/settings/pr_description_prompts.toml) tool, you can add the following to your `.pr_agent.toml` file:
+```
+[pr_description_prompt]
+system="""
+...
+"""
+user="""
+...
+"""
+```
+Note that the new prompt will need to generate an output compatible with the relevant [post-process function](./pr_agent/tools/pr_description.py#L137).
+
+### Working with GitHub Action
+You can configure settings in GitHub action by adding environment variables under the env section in `.github/workflows/pr_agent.yml` file. 
+Specifically, start by setting the following environment variables:
+```yaml
+      env:
+        OPENAI_KEY: ${{ secrets.OPENAI_KEY }} # Make sure to add your OpenAI key to your repo secrets
+        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # Make sure to add your GitHub token to your repo secrets
+        github_action.auto_review: "true" # enable\disable auto review
+        github_action.auto_describe: "true" # enable\disable auto describe
+        github_action.auto_improve: "false" # enable\disable auto improve
+```
+`github_action.auto_review`, `github_action.auto_describe` and `github_action.auto_improve` are used to enable/disable automatic tools that run when a new PR is opened.
+If not set, the default option is that only the `review` tool will run automatically when a new PR is opened.
+
+Note that you can give additional config parameters by adding environment variables to `.github/workflows/pr_agent.yml`, or by using a `.pr_agent.toml` file in the root of your repo, similar to the GitHub App usage.
+
+For example, you can set an environment variable: `pr_description.add_original_user_description=false`, or add a `.pr_agent.toml` file with the following content:
+```
+[pr_description]
+add_original_user_description = false
+```
+
+
+### Changing a model
+
+See [here](pr_agent/algo/__init__.py) for the list of available models.
+To use a different model than the default (GPT-4), you need to edit [configuration file](pr_agent/settings/configuration.toml#L2).
+For models and environments not from OPENAI, you might need to provide additional keys and other parameters. See below for instructions.
+
+#### Azure
+To use Azure, set in your .secrets.toml:
+```
+api_key = "" # your azure api key
+api_type = "azure"
+api_version = '2023-05-15'  # Check Azure documentation for the current API version
+api_base = ""  # The base URL for your Azure OpenAI resource. e.g. "https://<your resource name>.openai.azure.com"
+openai.deployment_id = ""  # The deployment name you chose when you deployed the engine
+```
+
+and
+```
+[config]
+model="" # the OpenAI model you've deployed on Azure (e.g. gpt-3.5-turbo)
+```
+in the configuration.toml
+
+#### Huggingface
+
+**Local**
+You can run Huggingface models locally through either [VLLM](https://docs.litellm.ai/docs/providers/vllm) or [Ollama](https://docs.litellm.ai/docs/providers/ollama)
+
+E.g. to use a new Huggingface model locally via Ollama, set:
+```
+[__init__.py]
+MAX_TOKENS = {
+    "model-name-on-ollama": <max_tokens>
+}
+e.g.
+MAX_TOKENS={
+    ...,
+    "llama2": 4096
+}
+
+
+[config] # in configuration.toml
+model = "ollama/llama2"
+
+[ollama] # in .secrets.toml
+api_base = ... # the base url for your huggingface inference endpoint
+```
+
+**Inference Endpoints**
+
+To use a new model with Huggingface Inference Endpoints, for example, set:
+```
+[__init__.py]
+MAX_TOKENS = {
+    "model-name-on-huggingface": <max_tokens>
+}
+e.g.
+MAX_TOKENS={
+    ...,
+    "meta-llama/Llama-2-7b-chat-hf": 4096
+}
+[config] # in configuration.toml
+model = "huggingface/meta-llama/Llama-2-7b-chat-hf"
+
+[huggingface] # in .secrets.toml
+key = ... # your huggingface api key
+api_base = ... # the base url for your huggingface inference endpoint
+```
+(you can obtain a Llama2 key from [here](https://replicate.com/replicate/llama-2-70b-chat/api))
+
+#### Replicate
+
+To use Llama2 model with Replicate, for example, set:
+```
+[config] # in configuration.toml
+model = "replicate/llama-2-70b-chat:2c1608e18606fad2812020dc541930f2d0495ce32eee50074220b87300bc16e1"
+[replicate] # in .secrets.toml
+key = ...
+```
+(you can obtain a Llama2 key from [here](https://replicate.com/replicate/llama-2-70b-chat/api))
+
+
+Also review the [AiHandler](pr_agent/algo/ai_handler.py) file for instruction how to set keys for other models.

+The default mode of CodiumAI is to have a single call per tool, using GPT-4, which has a token limit of 8000 tokens.
+This mode provide a very good speed-quality-cost tradeoff, and can handle most PRs successfully.
+When the PR is above the token limit, it employs a [PR Compression strategy](./PR_COMPRESSION.md).
+
+However, for very large PRs, or in case you want to emphasize quality over speed and cost, there are 2 possible solutions:
+1) [Use a model](#changing-a-model) with larger context, like GPT-32K, or claude-100K. This solution will be applicable for all the tools.
+2) For the `/improve` tool, there is an ['extended' mode](./docs/IMPROVE.md) (`/improve --extended`),
+which divides the PR to chunks, and process each chunk separately. With this mode, regardless of the model, no compression will be done (but for large PRs, multiple model calls may occur)
+
+### Appendix - additional configurations walkthrough
+
+
+#### Extra instructions
+All PR-Agent tools have a parameter called `extra_instructions`, that enables to add free-text extra instructions. Example usage:
+```
+/update_changelog --pr_update_changelog.extra_instructions="Make sure to update also the version ..."
+```
+
+#### Patch Extra Lines
+By default, around any change in your PR, git patch provides 3 lines of context above and below the change.
+```
+@@ -12,5 +12,5 @@ def func1():
+ code line that already existed in the file...
+ code line that already existed in the file...

+-code line that was removed in the PR
++new code line added in the PR
+ code line that already existed in the file...
+ code line that already existed in the file...
+ code line that already existed in the file...
+```
+
+For the `review`, `describe`, `ask` and `add_docs` tools, if the token budget allows, PR-Agent tries to increase the number of lines of context, via the parameter:
+```
+[config]
+patch_extra_lines=3
+```
+
+Increasing this number provides more context to the model, but will also increase the token budget.
+If the PR is too large (see [PR Compression strategy](./PR_COMPRESSION.md)), PR-Agent automatically sets this number to 0, using the original git patch.
+
+
+#### Azure DevOps provider
+To use Azure DevOps provider use the following settings in configuration.toml:
+```
+[config]
+git_provider="azure"
+use_repo_settings_file=false
+```
+
+And use the following settings (you have to replace the values) in .secrets.toml:
+```
+[azure_devops]
+org = "https://dev.azure.com/YOUR_ORGANIZATION/"
+pat = "YOUR_PAT_TOKEN"
+```

+
+### Configuration options
+
+Under the section 'pr_description', the [configuration file](./../pr_agent/settings/configuration.toml#L28) contains options to customize the 'describe' tool:
+
+- `publish_labels`: if set to true, the tool will publish the labels to the PR. Default is true.
+
+- `publish_description_as_comment`: if set to true, the tool will publish the description as a comment to the PR. If false, it will overwrite the origianl description. Default is false.
+
+- `add_original_user_description`: if set to true, the tool will add the original user description to the generated description. Default is false.
+
+- `keep_original_user_title`: if set to true, the tool will keep the original PR title, and won't change it. Default is false.
+
+- `extra_instructions`: Optional extra instructions to the tool. For example: "focus on the changes in the file X. Ignore change in ...".
+- To enable `custom labels`, apply the configuration changes described [here](./GENERATE_CUSTOM_LABELS.md#configuration-changes)
+### Markers template
+
+markers enable to easily integrate user's content and auto-generated content, with a template-like mechanism.
+
+For example, if the PR original description was:
+```
+User content...
+
+
+## PR Description:
+pr_agent:summary
+
+## PR Walkthrough:
+pr_agent:walkthrough
+```
+The marker `pr_agent:summary` will be replaced with the PR summary, and `pr_agent:walkthrough` will be replaced with the PR walkthrough.
+
+##### Example:
+```
+        env:
+          pr_description.use_description_markers: 'true'

+- `use_description_markers`: if set to true, the tool will use markers template. It replaces every marker of the form `pr_agent:marker_name` with the relevant content. Default is false.
+- `include_generated_by_header`: if set to true, the tool will add a dedicated header: 'Generated by PR Agent at ...' to any automatic content. Default is true.

+# Generate Custom Labels
+The `generate_labels` tool scans the PR code changes, and given a list of labels and their descriptions, it automatically suggests labels that match the PR code changes.
+
+It can be invoked manually by commenting on any PR:
+```
+/generate_labels

+<kbd><img src=./../pics/custom_label_published.png width="768"></kbd>
+
+### How to enable custom labels
+
+Note that in addition to the dedicated tool `generate_labels`, the custom labels will also be used by the `review` and `describe` tools.
+
+#### CLI
+To enable custom labels, you need to apply the [configuration changes](#configuration-changes) to the [custom_labels file](./../pr_agent/settings/custom_labels.toml):
+
+#### GitHub Action and GitHub App
+To enable custom labels, you need to apply the [configuration changes](#configuration-changes) to the local `.pr_agent.toml` file in you repository.
+
+#### Configuration changes
+ - Change `enable_custom_labels` to True: This will turn off the default labels and enable the custom labels provided in the custom_labels.toml file.
+ - Add the custom labels. It should be formatted as follows:
+
+```
+[config]
+enable_custom_labels=true

+
+<kbd><img src=./../pics/improve_comment.png width="768"></kbd>

+
+An extended mode, which does not involve PR Compression and provides more comprehensive suggestions, can be invoked by commenting on any PR:
+```
+/improve --extended
+```
+Note that the extended mode divides the PR code changes into chunks, up to the token limits, where each chunk is handled separately (multiple calls to GPT-4).
+Hence, the total number of suggestions is proportional to the number of chunks, i.e. the size of the PR.
+
+### Configuration options
+
+Under the section 'pr_code_suggestions', the [configuration file](./../pr_agent/settings/configuration.toml#L40) contains options to customize the 'improve' tool:
+
+- `num_code_suggestions`: number of code suggestions provided by the 'improve' tool. Default is 4.
+- `extra_instructions`: Optional extra instructions to the tool. For example: "focus on the changes in the file X. Ignore change in ...".
+- `rank_suggestions`: if set to true, the tool will rank the suggestions, based on importance. Default is false.
+
+#### params for '/improve --extended' mode
+- `num_code_suggestions_per_chunk`: number of code suggestions provided by the 'improve' tool, per chunk. Default is 8.
+- `rank_extended_suggestions`: if set to true, the tool will rank the suggestions, based on importance. Default is true.
+- `max_number_of_calls`: maximum number of chunks. Default is 5.
+- `final_clip_factor`: factor to remove suggestions with low confidence. Default is 0.9.
+
+
+#### A note on code suggestions quality
+
+- With current level of AI for code (GPT-4), mistakes can happen. Not all the suggestions will be perfect, and a user should not accept all of them automatically.
+
+- Suggestions are not meant to be [simplistic](./../pr_agent/settings/pr_code_suggestions_prompts.toml#L34). Instead, they aim to give deep feedback and raise questions, ideas and thoughts to the user, who can then use his judgment, experience, and understanding of the code base.
+
+- Recommended to use the 'extra_instructions' field to guide the model to suggestions that are more relevant to the specific needs of the project.
+
+- Best quality will be obtained by using 'improve --extended' mode.

+####  Incremental Mode
+For an incremental review, which only considers changes since the last PR-Agent review, this can be useful when working on the PR in an iterative manner, and you want to focus on the changes since the last review instead of reviewing the entire PR again, the following command can be used:
