Though it may seem cryptic at first, this version control system could change the way you work with text, whether you’re writing code, or a novel.
A List Apart gives a nice introduction to the GIT version control system. I used SVN for several years and recently made the switch to GIT. It’s a very powerful yes sometimes frustrating but once you get the hang of it you’ll smack yourself in head and wonder why you hadn’t used this before. (I’d suggest GitHub as a great repository service)
