 The `Volumio` platform allows you to control a [Volumio](https://volumio.org/) media player from Home Assistant.
 
-The preferred way to set up the Volumio platform is by enabling the [discovery component](/integrations/discovery/).
+## Configuration
 
-In case the discovery does not work, or you need specific configuration variables, you can add the following to your `configuration.yaml` file:
+Menu: **Configuration** -> **Integrations**.
 
-```yaml
-# Example configuration.yaml entry
-media_player:
-  - platform: volumio
-    host: homeaudio.local
-    port: 3000
-```
+In most cases, your Volumio device should be discovered and you'll simply need to click "Configure" to add it to Home Assistant.
 
-{% configuration %}
-name:
-  description: The name of the device.
-  required: false
-  default: Volumio
-  type: string
-host:
-  description: The IP address or hostname of the device.
-  required: true
-  default: localhost
-  type: string
-port:
-  description: The Port number of Volumio service.
-  required: true
-  default: 3000
-  type: integer
-{% endconfiguration %}
+If it's not discovered, you can click on the `+` sign to add an integration and then click on **Volumio**, and finally input the host and port.
+
+<div class='note'>
+Volumio versions 2.799 and below do not have a unique id when manually configured, so you will not be able to rename your entity or add your device to a area. If discovery does not work for you, it is advised to upgrade Volumio before configuring.
