Git commit opens blank text file, for what?

Question

In all the Git tutorials I\'ve read they say that you can do:

git init
git add .
git commit

When I do that I get a big text file opened up.

Answer 1

Being new to Terminal as well, "Escape and then ZZ" worked for me, I've been having this issue for months and also couldn't find a way around it.

Thanks TheGeoff for your simple advice!
