Fusion is probably the very first thing I install after a fresh install of Kodi, in every single device I have it.
It’s like a huge directory that allows us to later install a whole range of of repos and afterwards allows one to install an immense and diverse range of add-ons.
Here’s how to do it
Open Kodi and go to File Manager under the System tab
Select Add Source
Then type the following http://fusion.tvaddons.ag and select Done
After that just name it .fusion (the extra dot pulls it to first place)
and hit Done and OK.
This should work in every single Kodi installation despite it’s OS environment. Fusion is now alive and kicking.
