I just downloaded an OS X theme for CairoDock. I have already extracted it and put it in my documents folder (just so I know where it is). I am completely clueless on how to apply it. Thanks in advance!
Open the folder where you have downloaded the tarball with the theme. Do not extract it.
Then go to the Cairo Dock settings : right click on a dock >
You can also install the themes which are on the list at the left side of the tab by selecting the theme and then click on Apply at the bottom.
