I'm not sure if this is the right place for this, but it didn't seem to belong in the issue tracker since it isn't an issue with the framework itself.

There's a small documentation bug in the "Areas" section on the "First Concepts" page. It contains this text at the bottom which doesn't belong there:

> The first line creates a new area object named Sidebar, and the second line renders the contents of that area object. But what does that $c reference? $c refers to the collection object for the current page. The collection object consists of the current page’s blocks.

> In the code snippet above, we’re rendering the area object named Sidebar from whatever the current page / collection is.

Similar text appears earlier in the section and I assume this bit was supposed to be removed but wasn't.
