In our project we are following repo model as per <http://nvie.com/posts/a-successful-git-branching-model/> . 

I had been adding features into the develop branch until now, however now our project has created a release branch and I need to add a fix on that release branch. From what I have read , adding a hotfix will add the fix to my master branch and not the release branch. So how do I add a fix on my release branch ?
