 # Homelab Brisbane Home Page
+
+A simple `docker compose up` will launch this on your machine. The **home** page will be bound to `http://localhost:8080` and the **administration** page on `http://localhost:8081`.
+
+By default the contents of `dat.live` will be mounted, so changes made on the **administration** page will modify `dat.live/events.json`.
+
+If you want to experiment a little without interfering with the master calendar there is a `dat.test` folder that can be used instead by launching with...
+
+```bash
+HLBDAT=dat.test docker compose up
+```
+
+Even if you forget, you'd still need to `git add`, `git commit` and `git push` on your local machine. Moreover, *somebody* would need to `git pull` and `docker restart` on the production hosting environment before anybody else would see what you've done, so this is **super** low risk.
