+1.) Begin with both the Switch and Pro Controller off (Sleep Mode is fine).
+2.) Start the proxy.py script
+3.) Immediately after starting the script, press and hold the small, circular
+button on the back of the Pro Controller (near the USB-C input) until the
+player lights begin Flashing.
+4.) Once the script prints "Got Connection" and then "Waiting for Switch to
+connect...", start up your Switch and navigate to the "Pair/Change Grip" menu.
+5.) The Switch should connect the controller Proxy and the script should enter
+the mainloop.
+6.) Perform any actions with your controller that you want recorded.
+7.) Press Ctrl-C to end the script and dump the commands in the current
+working directory.
