# 🖥 System
This outlines the relevant system setup and packaging used to create Chevere.
# Operating System
Chevere is build and tested on Ubuntu (opens new window)
Chevere is PHP (opens new window) software.
- PHP packages (opens new window) from Ondřej Surý.
- PHP extensions (opens new window) provided by PECL (opens new window).
Packages and PECL provides the same convenience, but as packages are made for debian-based systems you should prefer PECL if you don't have a compatible system.
Packages vs PECL
Note that packages not only contain the software, it could also trigger other effects in the system.
