+## Deploying a pre-built image
+
+Every push to `main` that touches `server/` triggers a Gitea Actions
+workflow (`.gitea/workflows/server-docker-build.yml`) that builds this
+image and pushes it to this repo's Gitea Container Registry at
+`git.thumeit.com/tfaour/espresso-frame-server`. `docker-compose.yml`
+already points at that image, so a deploy host doesn't need this repo's
+build context at all -- just the compose file:
+
+```
+docker compose pull
+docker compose up -d
+```
+
+`docker compose build` (or `up --build`) still works too, for local
+iteration against your own Dockerfile changes.
