1. Extract folder to Documents/Sport Interactive/Football Manager 20##/graphics/kits/put in here!

( If there is no graphics folder there, create "graphics" )

2. FMXX - click 'Preferences' > 'Interface' > unticked 'Use caching to decrease page loading times & tick 'Reload skin when confirming changes' > click 'Reload Skin' for first your time.
