This project does not have a license, which means:
When you make a creative work (which includes code), the work is under exclusive copyright by default. Unless you include a license that specifies otherwise, nobody else can copy, distribute, or modify your work without being at risk of take-downs, shake-downs, or litigation. Once the work has other contributors (each a copyright holder), “nobody” starts including you.
This project does not have a license, which means:
I would recommend the GPLv3-or-later for this, since you definitely don't want a permissive license like MIT/Expat/X11.
