A basic placeholder page for brandguide.io

Following discussions this week, I think we're all in agreement that the marketing site doesn't need to be fully fleshed out before we hit this first milestone (preview release). However, a basic page with an elevator pitch phrase and a 'sign up for updates' prompt could do us some good. A couple of tweets collectively will be enough to get some of our designer friends and colleagues signed up—that way we can start building up a database of potential users.
