So on the main page of a wiki there is Featured page and Discord integrations and I want to know how to add them.
Check these out:
DiscordIntegrator | Fandom Developers Wiki | Fandom
AddRailModule | Fandom Developers Wiki | Fandom
These will help you.
The main/home page of the wiki does not have the same right rail as other pages. If you are taking specifically about the main/home page, see this help page instead.
Help:Main page column tags | Community Central | Fandom
What do you think?
