Tip request: `discord.py` command argument consumption

[Skelmis]

I think it would be nice to include a tips section of function arguments and how discord.py handles type hinting.
Furthermore, I think the following syntax should feature in a section since it differs from the *args, **kwargs standard

(ctx, *, args):

I think it'd be nice to have a section explaining how that works to consume the rest of the arguments and makes them into a regular string
