A Wiki is a special kind of website, one where everybody can contribute. Getting started working with a Wiki is a lot easier than you might imagine.
All Wiki websites use some form of "markup" to describe how documents look.
For example, to write in
bold you should simply surround the desired text with three tick marks. Like so:
'''bold'''
