The first time you start using github you'll need to run some commands
Clone the entire repository (about 400 MB) with: git clone https://github.com/tLDP/LDP
Go to the LDP repository on github and click on Fork. This will create your own copy of TLDP in your space that you can write to.
Lastly, link your local repository with your repository on github with git remote add upstream git@github.com/MyGithubID/LDP.git
