This plugin consist of two parts. This plugin is not for amateurs by itself like there is some tricky part regarding ChatterBot itself. If anyone is interesting I can provide ChatterBot Digital ocean snapshot for 30 EUR. You will have everythying setup there. So only lhc extension install will be required which is easy by itself.
After you have running ChatterBot you can configure Live Helper Chat extension itself.
As you can see at the bottom you can see. Bot suggested responses.
Yoiu can teach bot by entering questions and answers. Operators do not have to write any nasty regular expressions etc...
