Welcome to your wiki! This is the default page we've installed for your convenience. Go ahead and edit it.

Wiki features

This wiki uses the Creole syntax, and is fully compatible with the 1.0 specification.

The wiki itself is actually a git repository, which means you can clone it, edit it locally/offline, add images or any other file type, and push it back to us. It will be live immediately.

Go ahead and try:

$ git clone

Wiki pages are normal files, with the .wiki extension. You can edit them locally, as well as creating new ones.

Syntax highlighting

You can also highlight snippets of text, we use the excellent Pygments library.

Here's an example of some Python code:

def wiki_rocks(text):
    formatter = lambda t: "funky"+t
    return formatter(text)

You can check out the source of this page to see how that's done, and make sure to bookmark the vast library of Pygment lexers, we accept the 'short name' or the 'mimetype' of anything in there.

Have fun!
