+## Connect to a hue bridge
+
+In your code create a hue bridge instance
+
+```
+    func main() {
+        // ...
+        // create a bridge config
+        bridgeConf := &Config{
+            Username:         "YOUR_DEVICE_USERNAME", // check below for detailed instructions
+            BridgeAddr:       "YOUR_BRIDGE_IP_ADDR", // check below where to find the ip address of the hue
+            BridgeAddrScheme: "http",
+	    }
+
+        // create bridge
+        bridge := NewBridge(config)
+
+        // now do stuff with bridge
+        // get ligts as a map of lights over ids
+        lights, errLights := bridge.GetLights()
+        if errLights {
+            fmt.Println("Failed to get lights")
+        }
+
+        // Turn all lights on
+        for id, _ := range lights {
+            bridge.ToggleLight(id, true)
+        }
+    }
