Getting Started

Use Homebrew (http://brew.sh/) to install Git. If you have Homebrew installed, install Git via

$ brew install git

## First-Time Git Setup ##

Now that you have Git on your system, you’ll want to do a few things to customize your Git environment. You should have to do these things only once; they’ll stick around between upgrades. You can also change them at any time by running through the commands again.

Git comes with a tool called git config that lets you get and set configuration variables that control all aspects of how Git looks and operates. These variables can be stored in three different places:

/etc/gitconfig file: Contains values for every user on the system and all their repositories. If you pass the option--system to git config, it reads and writes from this file specifically. ~/.gitconfig f ile: Specific to your user. You can make Git read and write to this file specifically by passing the --global option. *config file in the Git di rectory (that is, .git/config) of whatever repository you’re currently using: Specific to that single repository. Each level overrides values in the previous level, so values in .git/config trump those in /etc/gitconfig.

Define your identity

$ git config --global user.name "Mike Jakobsen"
$ git config --global user.email "[email protected]"

$ git config --global core.editor VIM    
$ git config --global merge.tool vimdiff

Check the setup

$ git config --list
