Here are some helpful tips:

Create a new page, give it a name and type an 'opening line' for that page. Click save.

When you have more than 1 page you want to ORGANISE your NAVIGATION. This will be found down the left side of the page.
Click on edit navigation

On this blank page....
Insert a link by clicking the icon
Choose the wiki page from the drop box page
Click add link then enter so that the next link goes under the last (you can pick up and move around to the order you want)
Do this as many times as needed for each page you have made

If you want: Add a picture and add a link to the same pages you have made, one by one.
Remember to SAVE

Experiment!!!!!
