# Instructions to install LibrePaaS

## Recommendation
- API key on Namecheap (if you want to automatically buy domain name)

## Installation

First, you need a server.
You can take it from a cloud provider, like DigitalOcean or Scaleway and choose to spin up a VM with CoreOS already installed on it.

You can also buy a baremetal at [Hetzner](https://serverboerse.de/index.php?country=EN) as they are the cheapest options around. Follow these [instructions](INSTALL_HETZNER.md) in this case.

Copy this as your `user_data` and don't forget to change the hostname and your ssh key!

```
#cloud-config

hostname: $hostname
ssh_authorized_keys:
  - #your ssh public key here
