git clone https://github.com/username/username.github.io.git
git checkout source
Then we need to setup the deploy directory.

mkdir _deploy
cd _deploy
git init
git remote add -t master -f origin https://github.com/username/username.github.io.git
Done! Now we can make changes in source branch and use rake gen_deploy as usual.


if using zsh:
alias rake="noglob rake"
