Hello, Pepperminty.
As far as I can tell from "googling around", there is no genuine user guide for Linux Mint 13 Cinnamon desktop, yet.
So feel free to write it based on the
user guide for Linux Mint 13 Mate desktop.

Maybe the reason why no-one has bothered to write a user guide for Linux Mint 13 Cinnamon desktop, yet, is that Cinnamon is evolving too fast. So what you write today may no longer be up-to-date tomorrow. My system has got Cinnamon 1.4-UP3. Yet, Cinnamon 1.6 is already on its way.
Anyway, the closest that you can get to a user guide for Linux Mint 13 Cinnamon desktop may be by using
+ the
user guide for Linux Mint 13 Mate desktop for the common topics
+ the
Tips and Tricks for Linux Mint after Installation [Mint 13 Maya - Cinnamon Edition] for the Cinnamon topics
+ and by asking for help on more tricky problems here in the forum.
Kind regards,
Karl
