I would like to create a couple of pages for my open data site and then have links to them at the top of the site to the right of the default "Home" link. My home link is currently on the left side of the main menu area (I don't have the logo enabled). Looking around, I see code snippets and examples for customizing but I don't know where to go to start. Is there a step by step tutorial for where the code goes in the site editor and how to change it to add these links?
