WoW Petopia Community

I downloaded this and went to the website mentioned, but I cannot find how to install it? Usually you just unzip the files to the addon directory, but these files look different so I am guessing there is a different way to install?

When I downloaded the new editions of the addons, I treat it like any other addon and extract them to the addons folder. Sorry that's not more helpful.

I just recently started using this addon also, and I did exactly what Teigan described above. No hassle and it works perfectly.
