Help installing skin?

Well I clicked on the pmuskn file and then it says it was successfully installed, am I supposed to do anything else after that? (I went to Find Skin in the Skins button thing and found the pmuskn file and also clicked open. I did this several times but in the box of where the skins installed are supposed to be I can only find main theme)

Help? :’:

[edit] NEVERMIND GOT IT ON THANKS

Put the skin in the Skins folder in your client.
