Every time you work out how to do something, create a new page below by writing a page title in 'CamelCase', ie put the words together with no spaces and capitals for the first letter of each word. When you next save the page you'll see a question mark at the end of your new link. Click on it, and you will have made your new page (topic in wiki lingo!)
If you have a tip or trick that might help other people, add it to the TipsAndTricks page
Don't worry too much about organising the documentation - that can be done later
