+# BuildbotHammer
+
+This app automatically creates revert Pull Requests for failing builds in the
+CPython project. It monitors Buildbot for failing builds, identifies the
+commit that caused the failure, and creates a revert PR on GitHub. It also sends
+notifications to Discord.
+
+## Usage
+
+Run the script with:
+
+```
+python -m buildbothammer
+```
+
+The script will:
+1. Check Buildbot for failing builds
+2. For each failing build, it will:
+   - Identify the commit that caused the failure
+   - Create a new branch in your fork
+   - Revert the problematic commit
+   - Create a Pull Request to the main CPython repository
+   - Send a notification to the configured Discord channel
+
+## Configuration
+
+- `BUILDBOT_API`: The Buildbot API endpoint (default: "http://buildbot.python.org/api/v2")
+- `BUILDBOT_URL`: The Buildbot URL for generating links (default: "http://buildbot.python.org/#/")
+- `REPO_OWNER`: The owner of the main repository (default: "python")
+- `REPO_NAME`: The name of the repository (default: "cpython")
+- `FORK_OWNER`: Your GitHub username (default: "$REPO_OWNER")
+- `REPO_CLONE_PATH`: The directory for the local clone of the repository
