- Click the Edit icon (pencil) in the top right.
- Make your changes using the on-screen editor.
- At the bottom of the editor screen you'll see:
- Write a one line summary of what changed, i.e. "testing out editing"
- Commit directly to the
yourusername-branch-1
branch. - Push the big green button.
- That's create a what's called a Pull Request, which is just a name for "proposed a change".
- That takes you to the Pull Request page and you can write a note. "I'm making this change to understand how editing on GitHub works. Can you review my change, and if you agree with the edits I made, merge them in to the master document?"
