Just so I don't forget.
- Themes still refers to 1.9 https://docs.moodle.org/20/en/Standard_themes
- Confused with repositories https://docs.moodle.org/20/en/Private_files
- empty: https://docs.moodle.org/20/en/Working_with_files_and_folders
- Need links deleted as they are duplicated in the menu https://docs.moodle.org/20/en/Repositories
- https://docs.moodle.org/20/en/Video (etc) Need further work to make this complete.
