extend the documentation please

[VanDerLars]

This documentation is a joke. Please extend it, or remove the warning from the old documentation that there's a new version.

(The old one wasn't perfect as well)

What features do you think the new documentation is worse than the old one?

For example, for the Python script documentation, do you think you need to put different categories of functions to its own page instead of a single page?

Do you think the parameters of functions need to be explained in details?

I close this issue due to missing information.
