Document basic usage

Took me about half an hour before I got a working preview, since I assumed it would work much like FB (since it’s tagged that way). Tried pasting in a remote URL. Nothing. Switched to Visual mode, nothing. Tried linking a word properly, nothing. Inspected my javascript console and server error logs. Nothing. Finally, after reading comments in this support forum, discovered that Z-URL adds a new button to the formatting toolbar, and you have to paste your URL into that instead of pasting a URL normally.

Simple once you understand how it works, but since the common assumption is that it will work much like Facebook, would be very helpful to begin the plugin description with “Adds a new button to the formatting toolbar. Rather than pasting a URL normally, click the Z-URL ‘eyeball’ button and paste a URL into its insertion field.”
