 Then you will see halcmd:
 
-Enter '''loadusr arduino''' and then '''show pin'''
+Enter ```loadusr arduino``` and then ```show pin```
 
 All the Arduino generated Pins should now be listed and the State they are in. 
 You can click buttons now and if you run show pin again the state should've changed.
