Clarifying confusing phrasing

I'm reading the Getting Started, which is mostly great, but I found the phrasing of this paragraph really confusing--too many "this"s, not clear enough what they're referring to. (And the phrase "add a link to" is ambiguous; it could mean "put a link in this file" or "create a link that points to this file.") Once I figured out what that paragraph was saying, I figured it was worth trying to clarify it a little.
