+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 component to function, you will need to enable the Web Interface in the MPC-HC options dialog.
