+# Gitea
+
+[Gitlab](https://gitlab.com/) is a git repository host, similar to GitHub, but
+entirely self-hosted. More description forthcoming...
+
+## Configuration
+
+Copy `.env-dist` to `.env`, and edit variables accordingly. 
+
+ * `GITLAB_TRAEFIK_HOST` to the external domain name forwarded from traefik, eg.
+   `git.example.com`
+
+Config documention forthcoming...
+
+## Initial setup
+
+Bring up the service with `docker-compose up -d`
+Initial setup documentation forthcoming...
+
+```
+# Restart gitlab to get the config applied:
+docker-compose restart
+```
+
+## Notes
+
+Traefik listens for SSH connections on TCP port 2224 and forwards directly to
+the builtin Gitlab SSH service.
