Add open source license?

[maximecb]

Hello there. You didn't include an open source license in your repository, which makes it legally problematic to reuse this code. Just wondering if you'd be willing to add one. You can do this in less than five minutes.

If this code is for tutorial purposes, I would suggest the Unlicense, otherwise maybe BSD or MIT. https://unlicense.org/

Kind regards,
