How to use vim for git commits?

Question

vim

Good evening.
I decided to create an alias in .bashrc alias gc='git add --all && git commit'and chose vim as the default editor.
So, after inserting the alias, I get into vim, write my commit, but I can’t exit, not because I don’t know how, but because vim requires you to give the file a name.
The question is how to save the commit and exit without giving the file a name?
I mean there must be some options.
Thanks in advance.
