We can probably copy some/all of the description from the postgres docs rather than having to reinvent it: https://www.postgresql.org/docs/current/tutorial-window.html

Thanks for the feedback! I stitched together a description of window functions from the postgres docs and added a sub-section describing the syntax.
(EDIT: Just noticed that named windows are now supported, I'll add those the syntax description next) Named window functions are described also.
