In this short article, I’ll demonstrate the typical workflow for using a Git topic branch. If you’ve never heard of a topic branch, here’s a description from the excellent book, Pro Git:

Git rm FAQ: How do I tell Git not to track a file (or files) any more? That is, I want to remove the file from the Git repo?

While working on an application named "sarah" yesterday (named for the house known as "SARAH" in the tv series Eureka), I accidentally checked some files into Git that I didn't mean to. These were were primarily binary files in my project's "bin" and "target" directories.

git status FAQ: When I issue the "git status" command, I see the following "Your branch is ahead or origin/master ..." git message:

Git shortcuts FAQ: Can I create Git shortcuts (aliases) so I don't have to type out full Git commands like "git commit..."?

Git empty directories FAQ: How do I add an empty directory to a Git repository?

Short answer - you can't. (See below for the workaround.) The design of the Git staging area only accounts for files, as described in the Git FAQ, and other books like Pro Git.

Mac Git installation FAQ: How do I install Git on Mac OS X?

There are at least two different ways to install Git on Mac OS X systems, and I've used both of these methods. The first approach is to use a Mac GUI installer, and the second is to use the command-line MacPorts project to install Git on Mac OS X.
