How to install from a specific Git branch?

Hi There! In the Bailador project we use a branch called 'dev' for development and one called 'main' for releases. Or at least we try to. In the META.list of the ecosystem https://github.com/perl6/ecosystem/blob/master/META.list we have listed the 'main' branch: https://raw.githubusercontent.com/

How do you call the variable types?
