+**Important: Enable Git Commit Tracking**
+
+To see the git commit ID in the `/health` endpoint, you must enable "Include Source Commit in Build" in your application's General settings in Coolify:

+1. Go to your application in Coolify dashboard
+2. Navigate to General settings
+3. Enable "Include Source Commit in Build"
+4. Redeploy your application

 **Version Tracking:**
-- `git_commit`: Short Git commit SHA (7 characters) of the deployed code, auto-detected during build using `git rev-parse --short HEAD`
+- `git_commit`: Short Git commit SHA (7 characters) of the deployed code, provided by Coolify's `SOURCE_COMMIT` environment variable (first 7 characters). Returns "unknown" if "Include Source Commit in Build" is not enabled in Coolify settings.
 - `version`: Application version (defaults to 1.0.0, can be set via APP_VERSION env var)
 
 This allows AI agents and monitoring tools to verify which version is currently running. The short commit ID is industry standard for deployment tracking, providing a balance between uniqueness and readability.
 
+**To enable commit tracking:** Go to your application's General settings in Coolify and enable "Include Source Commit in Build", then redeploy.
