Add new Getting Started page

Modified content in start-en.hbs to match the new theme, 
Added page specific css in content/_base,scss
Modified colours in main/_base.scss and footer/_base.scss
Modified link colours in _variables.scss 
If I add an h2 to the large description it wouldn't look right because of the amount of text. The title is meant to be part of the "page banner" with the description. I would add an h2 to the summary tags but it won't pass the HTML validation hence why I'm using spans instead. Is there any other way to get around this?
