+
+### Application Settings
+
+The ***Application Settings*** menu has the following entries:
+
+![Settings > Application Settings](assets/img/settings_application.png)
+
+#### Color Output
+
+When enabled (the default), output to the console will use colors to highlight values and functionality. When disabled, all output is plain text. When using a limited serial console application, set this value to false.
+
+#### Board Name
+
+Set this value any name desired for the particular board. By default this value is ***empty***.
+
+#### Serial Console Format
+
+This property sets the output format for sensor/log data for the serial console. Available values include CSV, JSON and Disabled. The default value is ***CSV***.
+
+#### JSON Buffer Size 
+
+This is the size - in bytes - the application should use when building JSON formatted output. The default value is ***1600*** bytes. This value should only be adjusted if logging a large number of values to the serial console. 
+
+The maximum bytes used by the JSON system is displayed on the ***About*** page of the application (try using `!about` console command to see this value).
+
+#### Terminal Baud Rate 
+
+Use this value to change the baud rate settings for the serial console. Once changed this value might require a system restart to  take effect. The default value is ***115200***.
+
+#### Device Names
+
+When enabled (default is ***disabled***), attached devices have their address appended to the name. This is helpful to identify a particular board when two or more of the same board type are attached to the IoT Node board.
+
+#### Startup Delay
+
+When the IoT Node board starts up, an startup menu is displayed. This settings determines how long to display this menu. Setting this value disables the menu. 
+
+The startup menu has the following options:
+
+![Startup Menu](assets/img/settings_startupmenu.png)
+
+Pressing the indicted menu key selects that option. If the startup delay expires, a *normal* startup sequence occurs.
+
+##### Startup Menu Entries
+
+* 'n' = Normal startup sequence 
+* 'v' = Verbose output messaging is enabled at startup
+* 'a' = Disable qwiic device autoload 
+* 'l' = List the available qwiic/i2c drivers at startup (this list is deleted after startup)
+* 's' = Disable settings restore on startup 
+
+#### Verbose Messages
+
+When enabled, verbose output is enabled. This value is ***disabled*** by default.
+
+#### About...
+
+When selected, the system displays the ***About*** page for the application. This reflects the current status of system. This page is also displayed using the `!about` console command.

+
+#### Output Name
+
+When enabled, the board Name is included in the logged output. This value is ***disabled*** by default.
+
+#### Rate Metic

+### System Control
+
+The System Control page includes the following entries:
+
+![System Control](assets/img/settings_system.png)
+
+#### Device Restart
+
+When selected, the user is prompted to restart the device/system. This is also available using the `!restart` console command.
+
+#### Device Reset
+
+When selected, the user is prompted to reset the device/system. A device reset erases the current saved settings values and restarts the board/system. This is also available using the `!reset-device` console command.
