Formatting on the pages is obtained by using a simple syntax. Before making a new page or editing an existing page, you are encouraged to go to the playground to figure out how to make lists, headers, etc.
Using the H1, H2, etc headers will autocreate a table of contents for your page.
Before adding a page, check out the category guide to find the best place for your page.
Editing a page does not destroy the old page. Old versions of the page are saved preserving an edit history and the possibility to return to an earlier version
When editing a page, make sure and fill out the edit summary
