Setup for Github:Gist
Interestingly I have found that all you need to add your Gist entry is a Github account, there is no need to setup a repository and install the Github GUI if all you want to do is post code snippets. Once you have a Github account you can log into the Github Gist website and create all the gists you want. Very easy and a nice way to post well formatted code samples with no additional tweeking.
