How should I add the plugin to IntelliJ IDEA Community Edition?


I downloaded Once unzipped, I have a Scala folder with three subdirectories: launcher, lib and repo.

I tried to add it to IntelliJ IDEA Comunity Edition, by going to Setting menu, Plugins, Install Plugin from Disk, but when I browse to the folder where I unzipped the file, the IDE doesn't find any plugin.

Could someone please lend a hand with this?

Thanks in advance
