With git, you can create a web page with changed words highlighted. Red==removed, green==added.
When you have found a colleague, friend or a supervisor who can provide useful feedback, great!
When you make the changes and ask for more feedback, you don’t want to make your friend read the 50 pages again. And not everyone uses git (yet). Just create an HTML page with changes highlighted.
