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

When doing revision control, you should always explain what the changed you made are. Usually the first time you're have a comment such as "Initial Commit."

However in the long run you want to make a good comment for each commit. You will want something of the form:

Added experimental feature x.

X will increase the performance of feature Y in condition Z. Should you need X activate it with the -x or --feature-eks switches. This addresses feature request #1138.
