The on-wiki notifications provided by the Echo extension allow people to explicitly mention other users. There are some existing pages here and there on the wikis, but those pages are not necessary up-to-date and the existing documentation on www.mediawiki.org is currently a bit short.
This task is about understanding how Mentioning works. This might require you to play a bit with such Notifications.
You will create/edit a dedicated wiki page under Help:Notifications on mediawiki.org to:
- introduce / summarize the feature
- explain how it works, with examples
- detail cases where it will not work, with examples
- add any relevant information about it.
The page have to be concise, easy to understand and easy to translate.
