The easiest way to add a page is to search for the title you want. When it doesn't come up with anything, there will be a link that says "Create This Page". Click that, then it will bring you to the editing window. Just make sure you add the code posted above into that edit window. I'll go through and add some empty pages so you can go in and just click "edit" at the top.
There is a bit of a learning curve with this system, so please feel free to post your questions here, I'll try to be quick with replies.
