Instead of manually copy of the files to the Fusion360 complicated directories, go into Fusion360 after installing the Threadskeeper plugin and go into “Utilities”. There click on “Threadkeeper”, “Open Threadkeeper Directory”, copy the files there and then press “Sync”.
Anytime Fusion360 updates, threadkeeper will synchronize the files again.
Hope it helps you and others that didn’t know about this plugin 
It’s also compatible with Mac and Windows
