Basis for students learning to use git, the dominant modern version control tool

The git website has a page on installing git. The school computers already have git installed. For Linux users, you know what to do. For Mac users, I suggest using Homebrew as a package manager. You can ask it to install git with brew install git.

Here's the setup page on the website. A minimal setup involves recording your identity:

$ git config --global user.name "John Doe"
$ git config --global user.email [email protected]

Consider setting up these aliases for your convenience:

$ git config --global alias.at "status"
$ git config --global alias.logg 'log --graph --format="%C(auto)%h%d %s %Cgreen@%Creset{%ar}"'
