Hello,
Re. OneDrive, our most up-to-date documentation is here: OneDrive repository. Please let us know if anything needs updating.
The documentation Dropbox repository does indeed need documenting. It's on our to-do list; in the meantime perhaps MDL-52051 can help?
As always, help with improving the documentation is much appreciated. Anyone can log in to Moodle Docs with their moodle.org username and password and edit pages.
Hello Plínio. I have added some updated screenshots and instructions to the Dropbox repository documentation if they are helpful for you. As ever, if anyone can help improve the docs they are most welcome.
