+ * == DockerSpotifyClientPlugin Plugin ==
+ *
+ * This plugin helps you build docker containers using Spotify Docker Client.
+ *
+ * == Configuration ==
+ *
+ * In order to configure this plugin take a look at the available [[com.typesafe.sbt.packager.docker.DockerKeys]]
+ *
+ * == Requirements ==
+ *
+ * You need docker to have docker installed on your system.
+ * Check with a single command:
+ *
+ * {{{
+ * docker version
+ * }}}
+ *
+ *
+ * @note this plugin is not intended to build very customizable docker images, but turn your mappings
+ *       configuration in a docker image with almost no ''any'' configuration.
+ *
+ * @example Enable the plugin in the `build.sbt`
+ *          {{{
+ *              enablePlugins(DockerSpotifyClientPlugin)
+ *          }}}
