 # Oppo Blu-ray player Binding
 
-![Oppo logo](doc/oppo.png)
-
 This binding can be used to control the Oppo UDP-203/205 or BDP-83/93/95/103/105 Blu-ray player.
 Almost all features of the various models of this player line are supported by the binding.
 This binding was tested on a BDP-103 only, so there might be issues with other models that will need to be fixed.

 * On Linux, you may get an error stating the serial port cannot be opened when the Oppo binding tries to load.
 * You can get around this by adding the `openhab` user to the `dialout` group like this: `usermod -a -G dialout openhab`.
 * Also on Linux you may have issues with the USB if using two serial USB devices e.g. Oppo and RFXcom.
