please change clone URL to https:// instead of git://

[andreimpopescu]

The git clone git://... in README.markdown should be changed to https://...

As far as I can tell from https://github.blog/2021-09-01-improving-git-protocol-security-github/ the git:// URLs have been deprecated since 2022.

git:// urls have not been deprecated. The git:// protocol marker means that the git repository host will be connected to over ssh, while the https:// protocol marker means it will be connected to over https. Both protocols work, neither are deprecated.
