How to clone a git project from the website to your desktop?

The GitHub functionality to 'Clone in Desktop' has been replaced by a drag and drop feature which is not quite clear. The process to do this is explained here: http://joe.blog.freemansoft.com/2014/04/github-clone-to-desktop-with-windows.html

You could also install command-line tools. From the app, Preferences > Advanced > Install Command Line Tools
