Once you have Git installed on your machine, its time to set up a few things before starting using Git.

Git config is a tool that lets you get and set configuration variables that control every aspect of Git.

You can view your settings by command,

$ git config --list

When you are using Git first-time it's very important to set your user name and email address because git uses this information when making commits.

$ git config --global user.name “[firstname lastname]”
$ git config --global user.email “[valid-email]”

Note: Replace [firstname lastname] and [valid-email] with your identity information.

The use of –global option sets this information for every repository and git operations you perform on your machine.

You can override this configuration with a different name and email for a specific repository, you can do so by running the same command without the –global option from your repository directory.

You can setup your line ending preferences.

For Linux/Mac

$ git config --global core.autocrlf input
$ git config --global core.safecrlf true

And for Windows

$ git config --global core.autocrlf true
$ git config --global core.safecrlf true
