What is "add files via upload" commit message in GitHub repositories?

Question

I see lots of repositories in GitHub with this commit message: Add files via upload.

But I couldn't figure out how this (probably) automatic commit message is made. I looked around to find a clue, but I couldn't find any reference for setting this commit message as default or something.

Why and how some commits are done with this message?

That seems to be the GitHub "Upload files" web GUI feature, as described here:

Publish your updated webpage onto GitHub Pages:

From GitHub, click on “Upload files”

Where it says “Drag additional files here to add them to your repository”, drag and drop all the files in your webpage.Rproj folder:

• GitHub should now look like this.
  • Commit and push your changes:
  • At the bottom of the page where it says “Add files via upload”, write a commit message “Baby’s first commit”.
  • Click on “Commit changes”.
