Right now the README documentation is very weird because although most people are probably using Minima 2, the documentation explains mostly how to use Minima 3, but it also only shows how to install the Minima 2 theme using the gem 🤔. It would be nice to have installation instructions for both Minima 2 and 3, an explanation between the (small, albeit relevant) differences between both differences including the distribution method (Minima 3 is only available through GitHub AFAIK).

TLDR

Add to the README this line:

gem "minima", github: "jekyll/minima"

I'll fork minima this week and create a PR for these changes if no one does it before that.
