         Sourcebot requires the following environment variables to begin reviewing PRs through your new GitHub app:
 
         - `GITHUB_APP_ID`: The client ID of your GitHub app. Can be found in your [app settings](https://docs.github.com/en/apps/creating-github-apps/writing-code-for-a-github-app/quickstart#navigate-to-your-app-settings)
-        - `GITHUB_APP_WEBHOOK_SECRET`: A random webhook secret that you've set in your [app settings](https://docs.github.com/en/apps/creating-github-apps/writing-code-for-a-github-app/quickstart#navigate-to-your-app-settings). This can be anything (ex. `python -c "import secrets; print(secrets.token_hex(10))"` to generate a random secret)

         - `GITHUB_APP_PRIVATE_KEY_PATH`: The path to your app's private key. If you're running Sourcebot from a container, this is the path to this file from within your container
         (ex `/data/review-agent-key.pem`). You must copy the private key file into the directory you mount to Sourcebot (similar to the config file).
