title: and description: yaml properties in markdown files

[pitosalas]

I discovered that if I attach yaml to a README.md file (and any other file) the title and description are displayed beautifully as part of gitbooks standard template.

1. What other yaml properties might be implemented in the template?
2. How can I supply my own page template?

Thanks,

Here's what the .md file looks like

Here's what the resulting web page looks like

Dear GitBook, I'd love to see additional examples of this!
I'd be interested to see

1. What does the source file look like
2. What kind of syntax is allowed
3. How is the file rendered when live
