Why WAS Torque3D documentation so poor?

I would really like to get back into Torque, but I am finding the documentation to be so poor. For example, where is the explanation of callbacks? If I remember correctly, callbacks are HIGHLY important in Torque. Its great that there is an explanation of Torque syntax, but honestly synatax is VERY easy to figure out for anyone who has done even a little C/C++.

Perhaps I am just missing the quality documentation, any help would be appreciated. The only documentation regarding Torque3D I have found is at the following link:
