To configure git on your local machine, you need to run the following commands. Note that you need to replace "John Galt" and "jgalt@example.com" with your name and email, respectively.

$ git config --global user.name "John Galt"
$ git config --global user.email jgalt@example.com
$ git config --global push.default simple
$ git config --global color.ui true

If you're using OS X or Linux:

$ git config --global core.autocrlf input

If you're using Windows:

$ git config --global core.autocrlf true

$ git config -l
user.name=John Galt
user.email=jgalt@example.com
push.default=simple
color.ui=true
core.autocrlf=input
