+The `deutsche_bahn` sensor will give you the departure time of the next train for the given connection. In case of a delay, the delay is also shown. Additional `ATTRIBUTES` are used to inform about eg. the type of the train, price and if it is ontime. The data are coming from the [bahn.de](http://www.bahn.de/p/view/index.shtml) website.
+
+
+To enable this sensor, add the following lines to your `configuration.yaml` file:
