 All the hidden and not hidden features of GitHub.
 
+### Ignore Whitespace
+
+Adding `?w=1` to any diff URL will remove any changes only in whitespace, enabling you to see only that code that has changed.
+
+### Cloning a Repo
+
+When cloning a repo the `.git` can be left off the edge.
+
+```bash
+$ git clone https://github.com/tiimgreen/github-cheat-sheet
+```
+
+### Git wrapper
+
+[Hub](https://github.com/github/hub) is a command line tool that wraps git in order to extend it with extra features and commands that make working with GitHub easier.
+
+This allows you to do things like:
+
+```bash
+$ hub clone tiimgreen/toc
+```
+
+Which translates to:
+
+```bash
+$ git clone git://github.com/tiimgreen/toc.git
+```
+
+### git.io
+
+[git.io](http://git.io) is a simple URL shortner for GitHub.
+
