Instructions to install LibrePaaS

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 as they are the cheapest options around. You can filter servers with ssd.

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