Description
Howdy,
I get an 'error: experimental Nix feature 'nix-command' is disabled; add '--extra-experimental-features nix-command' to enable it'
Would you like me to add some text to the README.md on how to resolve that as a PR? Or just let the end users figure it out?
I did a nix develop github:typelevel/typelevel-nix#library --extra-experimental-features "nix-command flakes" and that worked well.
I suppose some of the other solutions are:
export NIX_CONFIG="experimental-features = nix-command flakes"
or editing your nix.conf. Let me know, and I can add a PR

Research direction
Start with README.md and review where development setup or Nix usage is documented. Verify the reported nix develop command and the alternative NIX_CONFIG or nix.conf approaches, then document the supported way to resolve the disabled nix-command and flakes features. Done means a user can find the README guidance and successfully run the development command.
