This page summarizes the basic git commands to work with CMSSW

• Generating SSH Keys: https://help.github.com/articles/generating-ssh-keys (skip the xclip part and directly open the id_rsa.pub with the editor)

• Initialize in your working directory (or in your home) an empty git repository:

    git init
    git config --global user.name "your name as in github"
    git config --global user.email "your email"
    git config --global core.editor "your favorite editor (ex. emacs)"
    #check your settings
    git config --list
    
* Check out git-cmssw commands in your home:

    git clone git@github.com:fwyzard/cms-git-tools.git
    #add this line to your ~.cshrc
    export PATH=$PWD/cms-git-tools:$PATH
    
* Setup a CMSSW area

    scram p CMSSW_X_X_X
    cd CMSSW_X_X_X/src
    cmsenv
    git cms-init
    
* To check out a package simply do

    git cms-addpkg "Package"
