+# Headscale
+Headscale is a self-hosted TailScale server. As far as I can tell, there isn't really a web frontend provided with the container image and all management actions are done on the command line
+
+## Using this kubernetes config
+Set the headscale domain name in `ingress.yml`. This config assumes you have cert-manager installed on your cluster, so if you want to provide HTTPS another way, feel free to comment out the `spec.tls` section (the annotation shouldn't affect anything, but you can comment it out as well if you want). Then look through the `config.yml` file and configure Headscale to fit your needs.
