the.com/rundown

means A condensed summary that hits the main points — quick to deliver, quicker to be mistaken for the full story.

from Built from 'run' plus 'down,' the sense comes from the idea of running down a list point by point, top to bottom — the same logic behind a sports 'rundown' of plays or scores. The adjective 'run-down' (exhausted, decrepit) is a separate cousin, from a clock or person winding down to a stop, so the summary sense and the worn-out sense share a spelling but not quite a story.
