Please add a license to this repo

[mbrukman]

First, thank you for sharing this collection of resources with us!

Could you please add an explicit LICENSE file to the repo so that it's clear under what terms the content is provided, and under what terms user contributions are licensed?

I see other repos in this org include licenses, so I'm guessing this was just an oversight, and should be easy to address.

Thanks!
