# Instructions to install libre.sh

Recommendation

- ssd on /dev/sda
- hdd on /dev/sdb
- hdd on /dev/sdc
- API key on Namecheap (if you want to automatically buy domain name)

## Installation

First, you need a server.
We recommend [Hetzner](https://serverboerse.de/index.php?country=EN) as they are the cheapest options around.
You can filter servers with ssd.

These instructions can also work on any VM/VPS/Hardware.
