Add basic operating instructions to the README

[JanHendrikVanHeusden]

There is a lot of technical information on all kinds of options, problems, bugs, installation etc. etc. in the README, very much appreciated the big effort you put in it! Lots of kudos!

Funny enough however, as far as I can see, there are no basic operating instructions, like:

• How do I run the client?
• How do I connect to my OneDrive account?
• How do I configure optons for the onedrive client?
• How do I determine which local folder to be used for synchronization?
• Should I run the onedrive client as a service? Why / why not? If so, how do I do that?
• ...

Google's AI gave me this (very short) information that I couldn't find (!) in the README:

To run the abraunegg OneDrive client on Linux, you first install it (preferably from your distro's repo or built from source for the latest version), then run commands like onedrive --synchronize or onedrive --monitor from the terminal, often using systemctl --user start onedrive-my-config to manage it as a service (etc. ...)

So my suggestion is to have this kind of info added to the README, preferably a link somewhere in the top of the page, so people do not go astray

I guess you missed this entire section in the readme
