Thanks, Max. When you choose a name for a new feature branch, it's usually best to have it relate to the changes you plan to commit to that branch. For example, in this case you could have called it: disqus-support

Also, it'd be helpful to include the theme name in your commit message. Perhaps something like: Add Disqus support to Brick theme
