I came across this feature request: https://meta.stackexchange.com/questions/97596/tell-new-users-to-read-the-tag-wiki
and I think there's a better post to close it as a duplicate of. the feature request's motivation is to prevent inappropriate usage of tags, which is the same as this much more viewed/popular feature request: https://meta.stackexchange.com/q/256114/997587
the post it's currently closed as a duplicate of is more general about letting users know that the tag wikis exist and could contain _general_ useful info- not specifically about guidance against misuse of the tag.
