Installing Git

First, try git on the command line. Most distributions will have it installed by default if other development tools are installed. If that fails, use the following to install git:

Debian / Ubuntu

sudo apt-get install git-core

Fedora

sudo yum install git-core

Windows (Cygwin)

Install the Cygwin package git. Do not attempt to use native Windows installations of git.

Windows (WSL)

We strongly recommend to install the package using the Linux distribution’s package manager. Native Windows installations of git may also work, but there are possible pitfalls.

macOS

Install the Xcode Command Line Tools.

Your Name and Email

The commit message of any change contains your name and email address to acknowledge your contribution and to have a point of contact if there are questions in the future; filling it in is required if you want to share your changes. The simplest way to do this is from the command line:

[[email protected] ~] git config --global user.name "Your Name"
[[email protected] ~] git config --global user.email [email protected]

This will write the settings into your git configuration file with your name and email:

[user]
    name = Your Name
    email = [email protected]

Of course you’ll need to replace Your Name and you@yourdomain.example.com with your actual name and email address.
