Currently all sources are located on GitHub. There are 2 branches: master and gh-pages. GitHub automatically provides web-hosting for the files in gh-pages branch, GitHub hosted game.

Game development is happening in master branch, periodically next stable version is copied to gh-pages.

Create a remote named "origin" pointing at the GitHub repository and pull sources from master branch:

git remote add origin https://github.com/curoles/x0game.git
git pull origin master

Merge from master to gh-pages:

mkdir gh-pages/
cd gh-pages/
git init 
git remote add origin https://github.com/curoles/x0game.git
git checkout -b gh-pages origin/gh-pages
git fetch
git merge origin/master
git commit -a -m "master->gh-pages"
git push
