Just wantet to ask if https://wiki.unity3d.com/index.php/Main_Page is the proper wiki for unity since its looking really scuffed.
All content on the wiki is licensed under CC-BY-SA. That makes it nearly unusable. Additionally, there's some awful code there. For example, once upon a time I used Json writer/parser from there, the performance was atrocious. Given that the wiki fails to properly display formatting in my browser, It is probably abandoned and I would recommend to avoid it.
