@@ -64,6 +64,12 @@ This project is built with:
 
 Simply open [Lovable](https://lovable.dev/projects/5ee9d1e7-af25-47e9-ab4c-bdbca4554e32) and click on Share -> Publish.
 
+### Forgejo and Dokploy
+
+Pushes and pull requests targeting `main` are verified by the Forgejo Actions workflow in `.forgejo/workflows/ci.yml`. The production container is built from `Dockerfile` and serves the Vite output with NGINX, including React Router fallback handling.
+
+Dokploy is connected to the `Websites/interactives` Forgejo repository with autodeploy enabled. A successful push to `main` triggers a fresh Dockerfile build and replaces the running service only after the image has built successfully.
+
 ## Can I connect a custom domain to my Lovable project?
 
 Yes, you can!
