+# Somnia.GuestLog Deployment
+
+## Deploy using docker-compose
+
+Use [docker-compose file](docker-compose.yaml) as example. Configure required enviroment variables.
+
+Notes:
+- By default, HTTP-only is deploy. Uncomment required sections to enable HTTPS (and mount required certs).
+- Reverse-proxies should work?
+
+[To-Be-Improved]
+
+## Manually update registry
+
+Container images are built by CI/CD pipelines and uploaded to the registry (**not yet!**).
+
+If required, a image can be manually built and uploaded to the registry (for testing or development purposes):
+```sh
+podman push [IMAGE_ID] [REGISTRY]/somnia/somnia-guestlog:[TAG]
+
+# Example:
+podman push localhost/somnia-guestlog:latest gitea.uberelectronnetwork.cc/somnia/somnia-guestlog:devbuild
+```
