Please be aware that the `master` branch is our currently considered stable system while `development` is used as a test bed for all upcoming changes for `master`. If you wish to run a stable, well tested system ensure you run `git checkout master`. If you decide to stick to the `development` branch with bleeding edge code and potential bugs, just `git clone` the project.
