What's the license for this code?

[lazerlabs]

I am following your video series and code to learn baremetal Raspberry pi and I might end up expanding on the OS.

however, your repository doesn't specify a license for the code, and if not specified it's usually safe to assume it's "all rights reserved". If that's the case, however, nobody can reuse any of your code.

Would you mind specify the license, if not the "all rights reserved"?

Thanks!
