At the bottom of the screen, there is a link called "Admin". And you should be on a page called "Admin Dashboard".

Then click "Wiki Features" in the "Wiki" Category.

Then you scroll down to the bottom of the page and you enable something called "Achievements". Enable that and you have badges!

Hooray! :)
