Documentation on Main Page Readme

Hello,

It would be nice to show a few small code excerpts on your readme. It'll be easier for someone just browsing your sample project to get an idea of how it works without additional steps.

Answering or showing the intent of the library for someone new is helpful. Here are some of my questions, that aren't apparent from the web documentation.

1. How do I create a simple message hud?
2. How do I cleanup the hud after I'm done?
3. How do I perform a complex message display?

Thanks,
Paul Solt

I added this to my fork, dhoerl/ATMHud, which I plan to support for a long time.
