+## Workflow Badge
+
+The Gitea Actions workflow badge is a badge that shows the status of the latest workflow run.
+It is designed to be compatible with [GitHub Actions workflow badge](https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/adding-a-workflow-status-badge).
+
+You can use the following URL to get the badge:
+
+```
+https://your-gitea-instance.com/{owner}/{repo}/actions/workflows/{workflow_file}/badge.svg?branch={branch}&event={event}&style={style}
