+=== Webcam Yolo Example
+
+Connect a known working webcam to the Venice SBC.
+The example used was a Logitech C930.
+
+Be sure it shows up using v4l2-ctl command:
+{{{
+gateworks@jammy-venice:~/apps/apps/Hailo-Application-Code-Examples/runtime/python/yolox_streaming_inference$ v4l2-ctl --list-devices
+Logitech Webcam C930e (usb-ci_hdrc.1-1.1):
+        /dev/video0
+
+}}}
+
+Update permissions of the webcam device on Venice SBC for all users just for the demo:
+{{{
+chmod 777 /dev/video0
+}}}
+
+Add a user to the Venice SBC other than root, as X11 doesn't work well as root
+{{{
+sudo adduser frank
+}}}
+
+SSH into the Venice SBC (headless) with a Linux desktop machine using X11 forwarding. This will allow a GUI window to popup on the Linux desktop machine because the Venice SBC has no monitor:
+{{{
+ssh frank@192.168.1.23-X #change IP to Venice SBC
+}}}
+
+From the ssh session on the desktop, run the example code like below:
+{{{
+gateworks@jammy-venice:~/apps/apps/Hailo-Application-Code-Examples/runtime/python/yolox_streaming_inference$ ./yolox_stream_inference.py 
+['0000:42:00.0']
+gateworks@jammy-venice:~/apps/apps/Hailo-Application-Code-Examples/runtime/python/yolox_streaming_inference$
