Set LICENSE so others know how to work with your code

Hello, thanks for sharing your playbook with the public!

Would it be possible to set a license for your project? Without a license it isn't clear what a user is allowed to do with your code. In the end it need to be considered proprietary and it is not allowed to re-use your code for other publicly shared projects.

Some Ideas:

• If you don't care what happens with your code at all and want to release it to the public domain, you could set CC0 (as in other projects where you collaborate) or UNLICENSE.
• If you want to get a copyright notice to you in other projects, you could set MIT.
• If you want that all future versions of your code get released as open source too, you could set GPL.
