+# CI Setup
+
+To enable automatic CI deployment for this repository, you need to do the following:
+
+1. Adapt `.drone.yml` such that the output is deployed to where you want to.
+
+   By default, this is `<repo-name>.party.leafbla.de`.
+
+1. Enable CI for the repository in [drone](https://drone.eterna.leafbla.de/).
+
+   Search the repository name in the search bar (you might need to click the "sync" button to make it show up) and click "activate repository"
+
+1. Add the required secrets so that the CI can deploy to oreburgh
+   - Secret Name: `rsync_key`
+
+     Secret Value: Find "pelipper ssh key" in Bitwarden and paste the content of `id_rsa`
+
+   - Secret Name: `docker_config`
+
+     Secret Value: Find "Docker registry credentials" in Bitwarden and paste the content of the note.
+
+The next time you push to the repository, the pipeline should run.
