The more details you can include in your campaign, the more the Kickstarter community will see that you are serious and dedicated to your product, campaign, and customers.

Provide additional details to the campaign description in the form of an FAQ (just link to a well developed page on your site) and any type of additional details or use cases - Pebble used over 1,200 words in its description. It went into detail about how you could customized the watch, how it actually works, what it can do, where the project's at, what rewards they're offering - then linked it all back to the site which they kept meticulously updated.

This will also serve as a tremendous help in the next milestone - external promotion.
