+## Installation
+
+---
+
+#### 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> review
+```
+
+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>"
+```
+
+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 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
+    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: ${{ secrets.GITHUB_TOKEN }}
+```
+
+2. Add the following secret to your repository under `Settings > Secrets`:
+
+```
+OPENAI_KEY: <your key>
+```
+
+The GITHUB_TOKEN secret is automatically created by GitHub.
+
+3. Merge this change to your main branch. 
+When you open your next PR, you should see a comment from `github-actions` bot with a review of your PR, and instructions on how to use the rest of the tools.
+
+4. You may configure PR-Agent by adding environment variables under the env section corresponding to any configurable property in the [configuration](./CONFIGURATION.md) file. Some examples:
+```yaml
+      env:
+        # ... previous environment values
+        OPENAI.ORG: "<Your organization name under your OpenAI account>"
+        PR_REVIEWER.REQUIRE_TESTS_REVIEW: "false" # Disable tests review
+        PR_CODE_SUGGESTIONS.NUM_CODE_SUGGESTIONS: 6 # Increase number of code suggestions
+```
+
+---
+
+#### Method 3: Run from source
+
+1. Clone this repository:
+
+```
+git clone https://github.com/Codium-ai/pr-agent.git
+```
+
+2. Install the requirements in your favorite virtual environment:
+
+```
+pip install -r requirements.txt
+```
+
+3. Copy the secrets template file and fill in your OpenAI key and your GitHub user token:
+
+```
+cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
+# Edit .secrets.toml file
+```
+
+4. Add the pr_agent folder to your PYTHONPATH, then run the cli.py script:
+
+```
+export PYTHONPATH=[$PYTHONPATH:]<PATH to pr_agent folder>
+python pr_agent/cli.py --pr_url <pr_url> review
+python pr_agent/cli.py --pr_url <pr_url> ask <your question>
+python pr_agent/cli.py --pr_url <pr_url> describe
+python pr_agent/cli.py --pr_url <pr_url> improve
+```
+
+---
+
+#### Method 4: 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 5: 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:
+    ```
+    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.
+
+---
+
+####  Deploy as a Lambda Function
+
+1. Follow steps 1-5 of [Method 5](#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](#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`

 ## Usage and Tools
 
-CodiumAI pr-agent provides two types of interactions ("tools"): `"PR Reviewer"` and `"PR Q&A"`.
+**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 different types of feedbacks.
+- 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.
-
-### PR Reviewer
-
-Here is a quick overview of the different sub-tools of PR Reviewer:
-
-- PR Analysis
-  - Summarize main theme
-  - PR description and title
-  - 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
-- 🔍 **Description and title:** Yes
-- 📌 **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.
-

-
-## Configuration
-
-The different tools and sub-tools used by CodiumAI pr-agent are easily configurable via the configuration file: `/settings/configuration.toml`.
-
-#### Enabling/disabling sub-tools:
-
-You can enable/disable the different PR Reviewer sub-sections with the following flags:
-
-```
-require_focused_review=true
-require_tests_review=true
-require_security_review=true
-```
-
-#### Code Suggestions configuration:
-
-There are also configuration options to control different aspects of the `code suggestions` feature.
-The number of suggestions provided can be controlled by adjusting the following parameter:
-
-```
-num_code_suggestions=4
-```
-
-You can also enable more verbose and informative mode of code suggestions:
-
-```
-extended_code_suggestions=false
-```
-
-This is a comparison of the regular and extended code suggestions modes:
-
-- **relevant file:** sql.py
-- **suggestion content:** Remove hardcoded sensitive information like username and password. Use environment variables or a secure method to store these values. [important]
-
-Example for extended suggestion:
-
-- **relevant file:** sql.py
-- **suggestion content:** Remove hardcoded sensitive information (username and password) [important]
-- **why:** Hardcoding sensitive information is a security risk. It's better to use environment variables or a secure way to store these values.
-- **code example:**
-  - **before code:**
-    ```
-    user = "root",
-    password = "Mysql@123",
-    ```
-  - **after code:**
-    ```
-    user = os.getenv('DB_USER'),
-    password = os.getenv('DB_PASSWORD'),
-    ```
-

+- 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.

 ## 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)
