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?

Per GitHub docs on licensing:

[...] without a license, the default copyright laws apply, meaning that you retain all rights to your source code and no one may reproduce, distribute, or create derivative works from your work. If you're creating an open source project, we strongly encourage you to include an open source license.

Thanks!
