Ye fair, it all depends on what markup you have and what features you use. Personally i dont think my markup of priiloader has any weird stuff that is specific to github, but i will have to check to be honest. If there was any special stuff id try to steer away from github specifics as much as i can, because i believe and work in a way it should always be possible to take away any part of a project and replace it with something else. It makes projects very flexible to change
