 ## ESP32 usage examples
 
 There are multiple ESP32 images available, some are build specifically for a target. Please check out the [list](https://github.com/nanoframework/nf-interpreter#firmware-for-reference-boards). You will need as well to know the COM port used by your device. Find [how to do this here](#finding-the-device-com-port-on-windows). Alternatively, you can as well list the available COM ports. If you list them first without the device to flash and then plugging the device, the additional port which will show up is the one for the device to flash. This method works for all OS:

+## Plain connection usage examples
+
+It's possible to update a nano device using  the same connection that is used for Visual Studio connection, meaning that no specialized connection is required (like JTAG, or JLink). This is only possible if the device has previously been flashed with a working nanoFramework firmware.
+
+### Update the CLR of a nano device
+
+To update the CLR of a nano device connected to a serial port to the latest available version.
+This will find the latest available firmware for the connected device and will update the CLR.
+
+```console
+nanoff --nanodevice --update --serialport COM9
+```
+
+### Deploy a managed application
+
+To deploy (or update) a managed application, the path to the managed application has to be provided.
+This example uses the binary format file that is generated by Visual Studio when building any nanoFramework C# application. Because it's possible to retrieve all the required details from the connected device no other configuration is required.
+
+```console
+nanoff --nanodevice --deploy --serialport COM9 --image "c:\dev\my awesome app\bin\debug\my_awesome_app.bin"
+```
+
+### Update the CLR of a nano device from a local file
+
+To update the firmware of a nano device with a local firmware file (for example from a build).
+This file has to be a binary file with a valid nanoCLR from a build. No checks or validations are performed on the file content.
+
+```console
+nanoff --nanodevice --serialport COM9 --binfile "C:\nf-interpreter\build\nanoclr.bin"
+```
+
+### Get details from a nano device
+
+To get the details of a nano device connected to a serial port.
+
+```console
+nanoff --nanodevice --devicedetails --serialport COM9
+```
+
 ## Common options
 
 ### Pre-check if target fits connected device
