   1. AX - AX has only one module nhaystack (download).
   2. N4 - N4 has two modules nhaystack-rt and nhaystack-wb (download).
2. Drag the nhaystack.jar into your modules folder (you may need to close/stop your station/workbench to add them)
3. Drag the NHaystackService from your Palette into your Services
   
4. Restart your station because its required for the changes to take effect
