Starting a New Page

It is unclear how to start a new Guide. I want to add a very few tips for running Fate Core RPG. The text says:

To add a page to this list, type (double square-brackets) Category:Guides (double-square brackets) at the bottom of the page you want to add to this list, ie on the bottom of the Pathfinder page.

But how do I start a new page? Does the text above mean I should type on an existing page and it will fragment off the old page? It is unclear.
