To add and use: Make sure your bookmarks toolbar is visible, then lovingly drag these buttons there:
Click each one when you want to add a page. You should be greeted with a pop-up form with the name and URL of the page prefilled. Fill out as much of the rest of the form as you can (especially the Description, Code/Doc URL, and Image URL), and submit.
(Note from Brent: I’ve only tested this in Chrome so far.)
