To the left of the screen you'll see a "table of contents" for this section of the class. This page is done in something known as frames...in general when you click on something in one frame the new content shows up in the other frame. We'll be starting with the link for "How Searching Works"

When you're done exploring the items to the left just click on the link that says "Next" and you'll go to the last page of the class.
