🐶

This is the commit header, it shows a hash which uniquely identifies the commit, and the author of the commit. In this case, I have just used emojis to represent the different people who are part of the book: 🐶 is the person writing code, and 🐱 is the person asking questions about the code.

Add scaffolding files

🐶

The first line of the commit message is called the subject, and conventionally it should be under 50 characters long, but this is not a limit.

These files aren't code, but are useful for the tools we use to edit and

communicate code.

The `.editorconfig` is used to tell text editors some basic information

about styling the file, so that it is more consistent between

developers.

The `.gitignore` tells git about some files/patterns that we don't want

it to track, for example output generated by the compiler. We don't want

to track this because it is different from machine to machine, and the

inputs to the compiler are tracked by git.

		🐶 This is the file called `.editorconfig`. The line starting with `@@` is not part of the file, it is called the “diff hunk header”. In this case it just says we are adding lines 1 to 13 to a new file: the `-0,0` means the file previously had no content; the `+1,13` means the hunk spans from line 1 to 13 lines below (including line 1).
