Class 'Plugin\Wiki-master\Base' not found

I can't install the Plugin.
After include in app/plugin folder i get a 500 error with message "Class 'Plugin\Wiki-master\Base' not found"

Can anyone help ?

The plugin needs to be installed in the app/plugins/wiki folder, not wiki-master. The downloaded archive includes the -master suffix in the name, but the plugin needs that suffix removed to load correctly.
