-## Configuration
-
-The different tools and sub-tools used by CodiumAI pr-agent are adjustable via the configuration file: `/pr-agent/settings/configuration.toml`.
-
-To edit the configuration of any tool, just add `--config_path=<value>` to you command.
-For example if you want to edit online the `pr_reviewer` configurations, you can run:
-```
-/review --pr_reviewer.extra_instructions="focus on the file xyz" --pr_reviewer.require_score_review=false ...
-```
-
-Any configuration value in `configuration.toml` file can be similarly edited.

+
+### 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).
+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.
+
+---
+
+### Appendix - **Debugging LLM API Calls**  
+If you're testing your codium/pr-agent server, and need to see if calls were made successfully + the exact call logs, you can use the [LiteLLM Debugger tool](https://docs.litellm.ai/docs/debugging/hosted_debugging). 
+
+You can do this by setting `litellm_debugger=true` in configuration.toml. Your Logs will be viewable in real-time @ `admin.litellm.ai/<your_email>`. Set your email in the `.secrets.toml` under 'user_email'.

-
-- 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.
-- The "PR Update Changelog" tool automatically updates the CHANGELOG.md file with the PR changes.

+
+### 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
+TBD
+
+### Appendix - additional configurations walkthrough

+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"
+```
