Added an explination for how to sync files

[ahcheing]

In the help forums it was mentioned that "..the documentation here blatantly skips over how to actually sync anything. It literally just says to install and start the app". I looked and saw that this was true, so I updated the documentation with my best understanding of how to use sync features.

Hello. Any updates on this?

Thanks for your pull request :+1:

The brief introduction for the files app sounds good to me, but the category for the document is groupware and the focus should be on syncing contacts and calendar.

@tobiasKaminsky @AlvaroBrey is there any other document we can use?
