The wiki of all wikis, the wiki wiki!

This wiki repo is desperately in need of some maintenance, so please contribute to it.

• Log in or sign up with GitHub
• Make changes, by opening a file in this repo and clicking edit. New to this? Confused?
• Propose these changes, by entering a suitable name and details for your changes, and clicking "Propose File Change". (this will create a new branch on your fork and make a pull request)
• We will review your changes, and if they are reasonable, we will accept them.
• Don't be afraid to make a few pull requests, but don't spam us either.

Please only make changes to pages you know lots about, don't change our pages where it is not necessary
