So apparently, I checked the Badges Fandom and it doesn't exactly explain how you add badges to a wiki. I really need help on that since I've started a Crossover Wiki. (If you know how, please message me here)
You need to request staff they enable Achievements, you can contact them here: https://fandom.zendesk.com/hc/en-us/requests/new you can also read more about Achievements on the help page: https://community.fandom.com/wiki/Help:Achievements
Oh, okay, thnx!
What do you think?
