-The `mpchc` platform allows you to connect a [Media Player Classic Home Cinema](https://mpc-hc.org/) to Home Assistant. It will allow you to see the current playing item, and respond to changes in the player's state.
-
-For this integration to function, you will need to enable the Web Interface in the MPC-HC options dialog.

-
-If the server running Home Assistant is not the same device that is running MPC-HC, you will need to ensure that the *allow access from localhost only* option is not set.
-
-<div class='note warning'>
-
-The MPC-HC web interface is highly insecure, and allows remote clients full player control file-system access without authentication. Never allow access to the Web UI from outside of your trusted network, and if possible [use a proxy script to restrict control or redact sensitive information](https://github.com/abcminiuser/mpc-hc-webui-proxy).
-
-</div>
-
-To add MPC-HC to your installation, add the following to your `configuration.yaml` file:
-
-```yaml
-# Example configuration.yaml entry
-media_player:
-  - platform: mpchc
-    host: http://192.168.0.123
-```
-
-{% configuration %}
-host:
-  description: The host name or IP address of the device that is running MPC-HC.
-  required: true
-  type: string
-port:
-  description: The port number of the device.
-  required: false
-  default: 13579
-  type: integer
-name:
-  description: The name of the device used in the frontend.
-  required: false
-  default: MPC-HC
-  type: string
-{% endconfiguration %}
