This theme work only with SmartLauncher, and at the moment it only changes the appearance of the the drawer.
You can download SmartLauncher here: https://play.google.com/store/apps/details?id=ginlemon.flowerfree
I suggest to use it with ADW Faenza, download here: https://play.google.com/store/apps/details?id=ginlemon.adw.faenza
To use it, open smart launcher, enter in the preferences, select Drawer, then Global theme.
