How to switch to the refactoring branch?

[ghost]

Do I have to install another version of Gamehub or can i do that in Gamehub itself.
Cause in the AUR I only found Gamehub and Gamehub-git.

If you want to test refactoring branch in ArchLinux:

1. Download the gamehub-git PKGBUILD file.
2. Replace the branch name in the source line (dev -> refactoring).
3. Run makepkg
4. Install the resulting .pkg.

It is in development and it's not really usable now.
You need to manually build it, see @neuromancer's answer how to do it on Arch.
