 ## 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 personal access token (classic) with the repo scope.
+
+There are several ways to use PR-Agent:

+### 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:
 
+For GitHub:
 ```
 docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent --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 --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.
 
 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> ask "<your question>"
 ```
+Note: If you want to ensure you're running a specific version of the Docker image, consider using the image's digest. 
+The digest is a unique identifier for a specific version of an image. You can pull and run an image using its digest by referencing it like so: repository@sha256:digest. Always ensure you're using the correct and trusted digest for your operations.
+
+1. To request a review for a PR using a specific digest, run the following command:
+```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
+```
+
+2. To ask a question about a PR using the same digest, run the following command:
+```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> ask "<your question>"

+
+### Method 7 - 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
+```
+
+---
+
+### Method 8 - 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=$(python -c "import secrets; print(secrets.token_hex(10))")
+```
+3. Follow the instructions to build the Docker image, setup a secrets file and deploy on your own server from [Method 5](#method-5-run-as-a-github-app) steps 4-7.
+4. In the secrets file, fill in the following:
+    - Your OpenAI key.
+    - In the [gitlab] section, fill in personal_access_token and shared_secret. The access token can be a personal access token, or a group or project access token.
+    - Set deployment_type to 'gitlab' in [configuration.toml](./pr_agent/settings/configuration.toml)
+5. Create a webhook in GitLab. Set the URL to the URL of your app's server. Set the secret token to the generated secret from step 2. 
+In the "Trigger" section, check the ‘comments’ and ‘merge request events’ boxes. 
+6. Test your installation by opening a merge request or commenting or a merge request using one of CodiumAI's commands.
+
+
+
+### Method 9: Run as a Bitbucket Pipeline
+
+
+You can use our pre-build Bitbucket-Pipeline docker image to run as Bitbucket-Pipeline.
+
+1. Add the following file in your repository bitbucket_pipelines.yml
+
+```yaml
+  pipelines:
+    pull-requests:
+      '**':
+        - step:
+            name: PR Agent Pipeline
+            caches:
+              - pip
+            image: python:3.8
+            services:
+              - docker
+            script:
+              - git clone https://github.com/Codium-ai/pr-agent.git
+              - cd pr-agent
+              - docker build -t bitbucket_runner:latest -f Dockerfile.bitbucket_pipeline .
+              - docker run -e OPENAI_API_KEY=$OPENAI_API_KEY -e BITBUCKET_BEARER_TOKEN=$BITBUCKET_BEARER_TOKEN -e BITBUCKET_PR_ID=$BITBUCKET_PR_ID -e BITBUCKET_REPO_SLUG=$BITBUCKET_REPO_SLUG -e BITBUCKET_WORKSPACE=$BITBUCKET_WORKSPACE bitbucket_runner:latest
+```
+
+2. Add the following secret to your repository under Repository settings > Pipelines > Repository variables.
+OPENAI_API_KEY: <your key>
+BITBUCKET_BEARER_TOKEN: <your token>
+
+3. To get BITBUCKET_BEARER_TOKEN follow these steps
+  So here is my step by step tutorial
+  i) Insert your workspace name instead of {workspace_name} and go to the following link in order to create an OAuth consumer.
+
+      https://bitbucket.org/{workspace_name}/workspace/settings/api
+
+      set callback URL to http://localhost:8976 (doesn't need to be a real server there)
+      select permissions: repository -> read
+
+  ii) use consumer's Key as a {client_id} and open the following URL in the browser
+
+      https://bitbucket.org/site/oauth2/authorize?client_id={client_id}&response_type=code
+
+  iii)
+      after you press "Grant access" in the browser it will redirect you to
+
+      http://localhost:8976?code=<CODE>

-## Usage and Tools
-
-**PR-Agent** provides five types of interactions ("tools"): `"PR Reviewer"`, `"PR Q&A"`, `"PR Description"`, `"PR Code Sueggestions"` and `"PR Reflect and Review"`.
-
-- The "PR Reviewer" tool automatically analyzes PRs, and provides various types of feedback.
-- The "PR Q&A" tool answers free-text questions about the PR.
-- The "PR Description" tool automatically sets the PR Title and body.
-- The "PR Code Suggestion" tool provide inline code suggestions for the PR that can be applied and committed.
-- The "PR Reflect and Review" tool initiates a dialog with the user, asks them to reflect on the PR, and then provides a more focused review.

+## 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 - a minimal requirement for each open-source model is to have 8k+ context, and good support for generating JSON as an output)
-- [x] Support other Git providers, such as Gitlab and Bitbucket.
-- [ ] Develop additional logic for handling large PRs, and compressing git patches
+- [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:
   - [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
   - [ ] ...

+
+### Introduction
+
+There are 3 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
+
+See the [installation guide](/INSTALL.md) for instructions on how to setup your own PR-Agent.
+
+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.
+
+**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"
+`
+
+[//]: # (** 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 cli.py --pr_url=<pr_url>  review`
+- **Describe**:     `python cli.py --pr_url=<pr_url>  describe`
+- **Improve**:      `python cli.py --pr_url=<pr_url>  improve`
+- **Ask**:          `python cli.py --pr_url=<pr_url>  ask "Write me a poem about this PR"`
+- **Reflect**:      `python cli.py --pr_url=<pr_url>  reflect`
+- **Update Changelog**:      `python cli.py --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 cli.py --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.
+
+
+### 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 repo will be initially loaded.
+
+#### GitHub app automatic tools
+The [github_app](pr_agent/settings/configuration.toml#L56) section defines GitHub app specific configurations. 
+An important parameter is `pr_commands`, which is a list of tools that will be **run automatically when a new PR is opened**:
+```
+[github_app]
+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, 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.
+
+However, 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.
+
+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.
+
+#### 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. 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
+        github_action.auto_review: "true" # Enable auto review
+        github_action.auto_describe: "true" # Enable auto describe
+        github_action.auto_improve: "false" # Disable auto improve      
+```
+specifically, `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.
+
+
+### Appendix - additional configurations walkthrough
+
+#### Changing a model
+See [here](pr_agent/algo/__init__.py) for the list of available models.
+
+#### Azure
+To use Azure, set: 
+```
+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"
+deployment_id = ""  # The deployment name you chose when you deployed the engine
+```
+in your .secrets.toml
+
+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.
+
+#### 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 ..."
+```
+
+#### 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"
+```
+
+#### Similar issue tool
+
+[Example usage](https://github.com/Alibaba-MIIL/ASL/issues/107)
+
+<img src=./pics/similar_issue_tool.png width="768">
+
+To enable usage of the '**similar issue**' tool, you need to set the following keys in `.secrets.toml` (or in the relevant environment variables):
+```
+[pinecone]
+api_key = "..."
+environment = "..."
+```
+These parameters can be obtained by registering to [Pinecone](https://app.pinecone.io/?sessionType=signup/).
+
+- To invoke the 'similar issue' tool from **CLI**, run:
+`python3 cli.py --issue_url=... similar_issue`
+
+- To invoke the 'similar' issue tool via online usage, [comment](https://github.com/Codium-ai/pr-agent/issues/178#issuecomment-1716934893) on a PR:
+`/similar_issue`
+
+- You can also enable the 'similar issue' tool to run automatically when a new issue is opened, by adding it to the [pr_commands list in the github_app section](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L66)
