1) Attach the camera on top of your monitor and adjust it according to your liking. 2) Plug the other end into a USB port on your computer. That’s it! After I plugged it in, the webcam was instantly “found” by the computer, “installed itself”, and was instantly shown in Skype as the default webcam to use for video calls. Perfect!
