+# MPD Binding
+
+[Music Player Daemon (MPD)](http://www.musicpd.org/) is a flexible, powerful, server-side application for playing music. Through plugins and libraries it can play a variety of sound files while being controlled by its network protocol. 
+
+With the openHAB MPD binding you can control Music Player Daemons.
+
+
+## Supported Things
+
+This binding supports one ThingType: mpd
+
+## Discovery
+
+If zeroconf is enabled in the Music Player Daemon, it is discovered. Each Music Player daemon requires a unique zeroconf_name for correct discovery.
+
+
+## Thing Configuration
+
+The ThingType mpd requires the following configuration parameters:
+
+| Parameter Label | Parameter ID | Description                                                              | Required |
+|-----------------|--------------|--------------------------------------------------------------------------|----------|
+| IP Address      | ipAddress    | Host name or IP address of the Music Player Daemon                       | yes      |
+| Port            | port         | Port number on which the Music Player Daemon is listening. Default: 6600 | yes      |
+| Password        | password     | Password to access the Music Player Daemon                               | no       |
+
+
+## Channels
+
+The following channels are currently available:
+
+| Channel Type ID | Item Type | Description               |
+|-----------------|-----------|---------------------------|
+| control         | Player    | Start/Pause/Next/Previous |
+| volume          | Dimmer    | Volume in percent         |
+| stop            | Switch    | Stop playback             |
+| currentalbum    | String    | Current album             |
+| currentartist   | String    | Current artist            |
+| currentname     | String    | Current name              |
+| currentsong     | Number    | Current song              |
+| currentsongid   | Number    | Current song id           |
+| currenttitle    | String    | Current title             |
+| currenttrack    | Number    | Current track             |
