-Because it wraps [an API](https://github.com/public-transport/hafas-client/blob/6/readme.md#background) of [Deutsche Bahn](https://de.wikipedia.org/wiki/Deutsche_Bahn), it **includes most of the long-distance and regional traffic, as well as some international trains and local buses**.

 ## Why use this API?
 
 ### Realtime Data
 
-This API returns realtime data whenever its upstream, the [API for DB's mobile app](https://github.com/public-transport/hafas-client/blob/6/p/db/readme.md), provides it.

 ## installing & running
 
-`db-rest` expects a [Redis](https://redis.io/) server running on `127.0.0.1:6379` (default port), but you can set the `REDIS_URL` environment variable to change this.
+### access to Redis
+
+It is recommended that you let `bvg-rest` cache HAFAS responses within a [Redis](https://redis.io/) cache. To use this feature, set `$REDIS_URL` (e.g. to `redis://localhost:6379/1` when running Redis locally).
 
 ### via Docker
 
-A Docker image [is available as `derhuerst/db-rest:6`](https://hub.docker.com/r/derhuerst/db-rest:6).
