Submitting a wiki article is a request from day 1. Since our wiki is not accessible for everyone, you can create a wiki article on the forum and we will review it if it will find its way to the official wiki or Discovery. You can post the articles over here: https://forum.endeavouros.com/c/forum-website/wiki-entry/89
There also has been a request to put a Gaming category on the wiki and we’re going to create it after we made some technical changes in the wiki.
We really depend on article contributions for the Gaming category from all the gamers in our community to make it a strong feature.
The procedure is the same as the regular wiki articles, you can create one over here and then we will add it to our official wiki.
