Provide a link to the updated document
Beside the epic "who and how should we update this cheatsheet", which might be a nice-to-have follow up, I'd like to see a link to the official, updated, documentation shown in the cheatsheet, instead of the current red stripe that is not super helpful or meaningful for any user landing in that handy page.
This page is listed in various places of the Web, including articles and source code from alternative ad blockers, reports, case studies, as pretty much everyone supports our filters (or let's say these are the common de-facto standard base offer), and informing whoever lands there to better understand filters, that such page is not fully updated, seems like a good thing to do, so that filter authors, possible new contributors, etcetera, might have a better clue of the current state of our filters.
Thanks in advance for considering this change, which is something like:
This cheatsheet is outdated. Please read the current documentation here.
or something similar.
