LICENSE file?

[tokk-nv]

Hi Jack,

First off, kudos on your excellent tutorial - it's been a real asset.
I'm eager to leverage it for a project I'm working on.
However, before I proceed, I noticed there isn't a LICENSE file attached to this repository.

Adding one would provide clarity on how your work can be used and built upon by others.
Would you mind considering this addition? It would be greatly appreciated.

Thanks again for your great work!

Best regards,
Chitoku
