I can see the main page looks fairly good although wiki activity and discussions are not showing, the nav bar is organized. If you mean how to grow the wiki, just keep working on it. Perhaps you might want to find affiliate wikis or make a discord server for the wiki, sometimes that helps attract users. Also consider a revival of the wiki's twitter account, it seems last time is was used was in 2018, or simply remove it. How many active users and visits you get will usually depend on how popular the game is.
