+`rpi-sb-provisioner` also contains a monitoring application. This can be used to observe the progress of a device as it is being provisioned. It also allows for easy introspection of the log files and lists all completed and failed devices.
+The monitoring application supports both mouse or keyboard input. Navigation between boxes can be acheived by using the `tab` key or by clicking on the desired area.
 
 To run, type into a terminal window:
 
 ----
 $ monitor.sh
 ----
 
-The TUI will start up with 3 sections, triaging, keywriting and provisoning. If a device is connected, you will be able to watch it progress through each of the sections.
-The TUI also has two areas at the bottom, one for successfully completed provisions and one for failed provisions. Clicking on the device name will open up a log window, along with options to view the log files for each step of the provisioning service.
+The TUI will intialise with 2 rows, the top one showing the progress of a device throughout the process, with each of the columns being for devices in the following stages: triaging, keywriting and provisoning.
+When a device is connected, you will be able to watch it progress through each of the sections.
+The second row of the TUI also has two boxes at the bottom, the left being successfully completed provisions and the right for failed provisions.
+Clicking on the device name will open up a second window, with buttons to view the log files for each step of the provisioning service.
 To return to the main monitoring screen, just press the key `m`.
 To quit the app use the key combination `CTRL-C` or `q`.
