 ```yml
 env:
-  OCTOPUS_HOST: ${{ secrets.OCTOPUS_URL }}
-  OCTOPUS_API_KEY: ${{ secrets.OCTOPUS_API_KEY }}
-  OCTOPUS_SPACE: '<spaceid>'
+  OCTOPUS_API_KEY: ${{ secrets.OCTOPUS_API_KEY }} # API key used with Octopus Deploy instance
+  OCTOPUS_HOST: ${{ secrets.OCTOPUS_HOST }}       # address of Octopus Deploy instance (i.e. https://demo.octopus.app)
+  OCTOPUS_SPACE: '<spaceid>'                      # space ID to target
