+![Three stages and three steps between them]() When converting to git you have to get used to the fact that there are three steps before a commit is shared with colleagues.
 Most version control systems have only step, committing from the working copy to a shared server.
 In git you add files from the working copy to the staging area. After that you commit them to the local repo.
 The third step is pushing to a shared remote repository.
 After getting used to these three steps the branching model becomes the challenge.

+![Multiple long running branches and merging in all directions]() Since many organizations new to git have no conventions how to work with it, it can quickly become a mess.
 The biggest problem they run into is that many long running branches that each contain part of the changes are around.
 People have a hard time figuring out which branch they should develop on or deploy to production.
 Frequently the reaction to this problem is to adopt a standardized pattern such as [git flow](http://nvie.com/posts/a-successful-git-branching-model/) and [GitHub flow]()

 It advocates a master branch and a separate develop branch as well as supporting branches for features, releases and hotfixes.
 The development happens on the develop branch, moves to a release branch and is finally merged into the master branch.
