I am a newbie. How do I install Magit from its git repository? Where do you copy the repositories of Emacs packages? And how to get the correct path in Aquamacs?
Of course that is covered by the manual.
Personally I install all my packages as git submodules. To do that I run.
git submodule add --name magit email@example.com:magit/magit.git lib/magit
