I Googled “git”; https://git-scm.com/ was the first result.

I Googled “perl git”; http://perl5.git.perl.org/perl.git was the first result. Up in the upper right-hand corner, there was a git icon with a hyperlink to https://git-scm.com/.

So, I guess that is the way to start learning and using git.
