Gitbook works a bit like a wiki in that you can edit all pages freely, but unlike a wiki, it uses git's "everyone has their own branch" principle. That is to say that the changes you make are independent of everyone else's changes, and won't show up on the main (live) website until the branches are merged.
To some degree, this means that you can do whatever you want in your branch. That said, there's some things which make things easier for everyone involved:
