 Contributions welcome!
 :::
+
+Setting up in Unraid with docker is straigth forward and combined with `ofelia` we can schedule the containers easily.
+
+_HINT_: The provided Apps in Unraid are not maintained by us!
+
+Make sure to enable Advanced/extended view in Unraid (top right).
+
+- Configarr:
+
+  ```
+  Name: configarr (we need this later on)
+  Repository: configarr/configarr:latest # Recommendation: use tags like 1.9.0
+
+  (add volume mappings like your setups requires it. Example with <name> - <host/unraid path>:<container path>)
+  Config volume - /mnt/user/appdata/configarr/config:/app/config
+  Repo cache - /mnt/user/appdata/configarr/repos:/app/repos
+  Custom formats - /mnt/user/appdata/configarr/cfs:/app/cfs
+  Templates - /mnt/user/appdata/configarr/templates:/app/templates
+  ```
+
+  - Add other variables or mapping as your setup requires it
+  - Afterwards create the required files in the config volume `config.yml` and `secrets.yml` (check examples or this guide)
+
+- Ofelia (scheduler):
+
+  ```
+  Name: ofelia
+  Repository: mcuadros/ofelia:latest # Recommendation: use specific tags not latest
+  Post Arguments: daemon --config=/opt/config.ini
+
+  (add volume mappings like your setups requires it. Example with <name> - <host/unraid path>:<container path>)
+  Docker socket - /var/run/docker.sock:/var/run/docker.sock (Read Only)
+  Ofelia config file - /mnt/user/appdata/ofelia/ofelia.ini:/opt/config.ini (Read only)
+  ```
+
+  - Make sure to create the `ofelia.ini` file best before starting the container
+
+  ```ini
+  [job-run "run-configarr-existing-container"]
+  schedule = @every 10s # adjust as required. Recommendation every 3h or so
+  container = configarr # this is the name of container we gave
+  ```
+
+  - you can also activate `autostart` for ofelia
+
+![Unraid Setup with the containers](_images/unraid_setup.webp)
+
+Now start both containers.
+Check the logs if configarr works as expected (exit code should be 0).
+Ofelia should keep running and restarting the configarr in your defined interval.
+
+**Enjoy!**
