Under-documented classes?

I’m new to PyMC3. At skimming through the documentations, I’d like to be able to see the entire options for a function or an object. For example, the Uniform class is presented as
class pymc3.distributions.continuous.Uniform(lower=0, upper=1, *args, **kwargs)
But I see no information about the args and the kwargs. Also when I hover above it in VS Code, though I see the possible arguments I don’t find a description of what they mean.

I will deeply appreciate any further guidance.
