Some tags on Commons are clickable links that lead to (localized) info pages. e.g.:
If you click the link on the tag you will be redirected to a (localized) on-wiki info page via
The link is part of the i18n message that is used to have a short readable tag label and this i18n message can be overwritten on the wikis
So we could also consider
- overwriting that message on-wiki
- set a link to a (localized) info page
- add a short description to the feature on that page
Alternatively we could also "just" directly link to our general extension help page.
