# What is Chromebrew?
**Chromebrew** is an open-source package manager for ChromeOS like apt(Ubuntu) or yum (CentOS). 

Before Chromebrew, in order to use packages not provided in ChromeOS, you had to resort to Crouton. **Crouton** installs a full-fledged LinuxOS that you can use to install and work with any package you want. With Chromebrew, you can install and work with packages on the host, ChromeOS.   

Chromebrew is simply a Ruby script with some git involved. Therefore, you need to have both these things if you want to run Chromebrew on your ChromeOS.
