 ###### Address
-
 Enter the IP Address in the Address field. If you are connecting to a Windows PC, you must also provide the port number (typically 50443). To determine the correct address to specify:
-
 * HoloLens: Run the Settings application, select Network & Internet > Wi-Fi.
-
 * Windows PC : Run the Settings application, select Update & Security > For Developers.
 
-###### SSID and Key
+###### Username and Password
+If you wish to use a specific set of credentials for the device, fill out these controls. Doing so will override the default values.
 
+###### SSID and Key
 If you wish to set your device onto a specific network access point, enter the SSID and network key in these boxes.
 
-###### Update Connection
+###### Use Installed Device Certificate
+If you have previously downloaded and installed the device's root certificate, you can select this option to use it. Otherwise, the certificate wil be automatically downloaded, though it will not be installed.
 
+###### Update Connection
 Checking Update Connection instructs Windows Mixed Reality Commander to query the device for the first valid (non-169.x.x.x) IP address it reports. 
 
-If you specified an SSID, this value may change, and the connection update may fail. Please retry the connection again without setting the SSID and verify the correct network configuration in the Settings application.
+If you specified an SSID, this may cause the device to become unreachable if the PC does not have access to the new address.

-The additional options (…) button displays a menu that provide less common connection related functionality.
-
-**Reconnect to previous session**
