+# Sbus Binding
+
+This binding integrates Sbus devices with openHAB, allowing control and monitoring of Sbus-compatible devices over UDP.
+Sbus is a protocol used for home automation devices that communicate over UDP networks.
+The binding supports various device types including RGB/RGBW controllers, temperature sensors, and switch controllers.
+
+## Supported Things
+
+- `udp` - Sbus Bridge for UDP communication
+- `rgbw` - RGB/RGBW Controllers for color and brightness control
+- `temperature` - Temperature Sensors for monitoring environmental conditions
+- `switch` - Switch Controllers for basic on/off and dimming control
+
+## Discovery
+
+Sbus devices communicate via UDP broadcast, but manual configuration is required to set up the devices in openHAB.
+Auto-discovery is not supported at this moment.
+
+## Binding Configuration
+
+The binding itself does not require any special configuration.
+
+## Thing Configuration
+
+### Bridge Configuration
+
+The Sbus Bridge has the following configuration parameters:
