+The `bluesound` platform allows you to control your [Bluesound](http://www.bluesound.com/) HiFi wireless speakers and audio components from Home Assistant.
+
+If you want to automatically discover new devices, just make sure you have discovery: in your configuration.yaml file. To manually add a Bluesound device to your installation, add the following to your configuration.yaml file:
+
+
+```yaml
+# Example configuration.yaml
+media_player:
+  - platform: bluesound
+    hosts:
+      - host: 192.168.1.100
+```
+
+Configuration variables:
+
+- **hosts** (*Optional*): List with your bluesound devices
+  - **host** (*Required*): IP-address or hostname of the player
+  - **name** (*Optional*): The name of the device used in the frontend
+  - **port** (*Optional*): Port of communication to the device (default: 11000)
+  
+## Advanced configuration example
+  
+  ```yaml
+# Example configuration.yaml entry with manually specified addresses
+media_player:
+  - platform: bluesound
+    hosts:
+      - host: 192.168.1.100
+        name: bluesound_kitchen
+        port: 11000
+      - host: 192.168.1.131
+```
