Readme seems self-contradictory regarding what code to put in the html file

[pabrams]

At the heading Use the SDK, we are told to call VSS.init and after that call VSS.ready, and there is no mention of VSS.require. A little further down in the same file, at the heading HTML page, we are told to call VSS.init and then call VSS.require, and there is no mention of VSS.ready.

Why are there two different sections on which VSS calls to make from the HTML file? Which one should I follow?
