Project page is missing a README.md

It would be nice if the project featured a README.md file providing a brief overview of the project and some additional info such as how to download the app from the Play Store.

Both byheart-web and byheart-android include a README.md:

• https://github.com/Bryanx/byheart/blob/master/byheart-web/README.md
• https://github.com/Bryanx/byheart/blob/master/byheart-android/README.md

The root project doesn't include one, though.
