 ## Automated Tracking
 
-A [workflow](.github/workflows/gitea-tracker.yml) runs daily (and on-demand) to detect new Gitea releases. When a new version is found, it automatically creates a PR updating the matrix and badges with a **⏳ Pending Verification** status.
-
-### Webhook Setup (optional)
-
-To trigger the tracker immediately when Gitea publishes a release, configure a webhook on your Gitea instance:
-
-1. Go to **Site Administration → System Webhooks**
-2. Add a webhook with the type **Send Everything**
-3. Set URL to:
-   ```
-   https://api.github.com/repos/<YOUR_USER>/gitea-mail-templates/dispatches/gitea-release
-   ```
-4. Set **Authorization** header with a [GitHub PAT](https://github.com/settings/tokens) that has `repo` scope:
-   ```
-   Authorization: Bearer ghp_xxxxxxxxxxxx
-   ```
-5. Content type: `application/json`
-
-> The tracker also runs daily via cron (`0 8 * * *` UTC), so manual webhook setup is optional.
