-## History
-
-This project has tried two other OS flavors before settling on MicroOS. Fedora Server, and k3OS. The latter, k3OS, is now defunct! However, our code base for it lives on in the [k3os branch](https://github.com/kube-hetzner/terraform-hcloud-kube-hetzner/tree/k3os). Do not hesitate to check it out, it should still work.
-
-There is also a branch where openSUSE MicroOS came preinstalled with the k3s RPM from devel:kubic/k3s, but we moved away from that solution as the k3s version was rarely getting updates. See the [microOS-k3s-rpm](https://github.com/kube-hetzner/terraform-hcloud-kube-hetzner/tree/microOS-k3s-rpm) branch for more.

 ## Contributing
 
 🌱 This project currently installs openSUSE MicroOS via the Hetzner rescue mode, making things a few minutes slower. To help with that, you could **take a few minutes to send a support request to Hetzner, asking them to please add openSUSE MicroOS as a default image**, not just an ISO. The more requests they receive, the likelier they are to add support for it, and if they do, that will cut the deployment time by half. The official link to openSUSE MicroOS is <https://get.opensuse.org/microos>, and their `OpenStack Cloud` image has full support for Cloud-init, which would probably very much suit the Hetzner Ops team!
