 ## Working Effectively
 
 ### Bootstrap and Setup
+
 - Clone the repository
 - `npm install` -- takes 1-30 seconds depending on npm cache state. Works with Node.js 20.x but shows engine warnings (expects Node.js 22.x)
 - Create `.env` file for local development:
-  ```bash
-  echo 'APP_ID=12345
-  PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----
-  [valid PEM private key content]
-  -----END RSA PRIVATE KEY-----"
-  WEBHOOK_SECRET=test_webhook_secret_123
-  PORT=3000' > .env
-  ```
+    ```bash
+    echo 'APP_ID=12345
+    PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----
+    [valid PEM private key content]
+    -----END RSA PRIVATE KEY-----"
+    WEBHOOK_SECRET=test_webhook_secret_123
+    PORT=3000' > .env
+    ```
 
 ### Build and Test
+
 - `npm run lint` -- takes ~1.5 seconds. NEVER CANCEL. Uses ESLint with eslint-config-eslint
 - `npm test` -- takes ~3 seconds. NEVER CANCEL. Runs Jest with 284 tests achieving 98.31% coverage
 - Run the web server: `npm start` -- starts immediately on port 3000
 - Health check: `curl http://localhost:3000/ping` returns "PONG" in ~1.6ms
 
 ### Environment Requirements
+
 - Node.js 22.x preferred (works on 20.x with warnings)
 - npm 10.x
 - Environment variables for server operation:
-  - `APP_ID`: GitHub app ID (can be dummy value like 12345 for local testing)
-  - `PRIVATE_KEY`: Valid PEM private key (required format, can be test key for local development)
-  - `WEBHOOK_SECRET`: Webhook secret (can be dummy value for local testing)
-  - `PORT`: Server port (optional, defaults to 3000)
+    - `APP_ID`: GitHub app ID (can be dummy value like 12345 for local testing)
+    - `PRIVATE_KEY`: Valid PEM private key (required format, can be test key for local development)
+    - `WEBHOOK_SECRET`: Webhook secret (can be dummy value for local testing)
+    - `PORT`: Server port (optional, defaults to 3000)
 
 ## Validation
 
 ### Manual Testing Requirements
+
 - ALWAYS run the full test suite after making changes: `npm test`
 - ALWAYS run linting before committing: `npm run lint`
 - Test server startup: `npm start` and verify health check responds: `curl http://localhost:3000/ping`
 - For plugin changes, run relevant test files: `npm test tests/plugins/[plugin-name]/index.js`
 
 ### Critical Timing Requirements
+
 - **NEVER CANCEL** any commands - all operations complete quickly
 - npm install: 1-30 seconds (set timeout to 60+ seconds)
 - npm test: ~3 seconds (set timeout to 30+ seconds)

 ### Plugin Development

 ### Adding New Plugins
+
 1. Create plugin file in `src/plugins/[plugin-name]/index.js`
 2. Add plugin to exports in `src/plugins/index.js`
 3. Add plugin to enabled list in `src/app.js`
 4. Create tests in `tests/plugins/[plugin-name]/index.js`
 5. Follow existing plugin patterns using Probot event handlers

 ## Troubleshooting
 
 ### Node.js Version Warnings
+
 - Repository expects Node.js 22.x but works on 20.x with warnings
 - Engine warnings are normal and do not prevent functionality
 - All commands and tests work correctly despite version mismatch
 
 ### Server Won't Start
+
 - Ensure `.env` file exists with required environment variables
 - `PRIVATE_KEY` must be valid PEM format (can be test key for local development)
 - Server defaults to port 3000, check for port conflicts
 
 ### Test Failures
+
 - Run `npm install` to ensure dependencies are current
 - Check that changes don't break existing plugin functionality
 - Verify new tests follow existing patterns in `tests/plugins/` structure
 
 ### Deployment Notes
+
 - Production deployment uses Dokku to github-bot.eslint.org
 - Health check endpoint: https://github-bot.eslint.org/ping
 - Webhook URL: /api/github/webhooks (Probot default)
