"Desktop User Guide" - is it in the menu?

It popped up(under the above name) and looks like it might be useful, but I can’t find it in the menu, or in the repositories. According to the synaptic I have already installed an item called “Mate Desktop user guide”, but again, I don’t find it in the menus.

You can get it under System > Help

Silly me. I was looking for it under it’s name. Thanks, Ele.
