-curl 'https://v5.db.transport.rest/stops/8010159/arrivals?duration=10' -s | jq
-```
-
-
-## `GET /journeys`
-
-Uses [`hafasClient.journeys()`](https://github.com/public-transport/hafas-client/blob/5/docs/journeys.md) to **find journeys from A (`from`) to B (`to`)**.
-
-`from` (A), `to` (B), and the optional `via` must each have one of these formats:
-
-- as stop/station ID (e.g. `from=8010159` for *Halle (Saale) Hbf*)
-- as a POI (e.g. `from.id=991561765&from.latitude=51.48364&from.longitude=11.98084` for *Halle+(Saale),+Stadtpark+Halle+(Grünanlagen)*)
-- as an address (e.g. `from.latitude=51.25639&from.longitude=7.46685&from.address=Hansestadt+Breckerfeld,+Hansering+3` for *Hansestadt Breckerfeld, Hansering 3*)
-
-### Pagination
-
-Given a response, you can also fetch more journeys matching the same criteria. Instead of `from*`, `to*` & `departure`/`arrival`, pass `earlierRef` from the first response as `earlierThan` to get journeys "before", or `laterRef` as `laterThan` to get journeys "after".
-
-Check the [`hafasClient.journeys()` docs](https://github.com/public-transport/hafas-client/blob/5/docs/journeys.md) for more details.
-
-### Query Parameters
-
-parameter | description | type | default value
-----------|-------------|------|--------------

-### Examples
-
-```shell
-# stop/station to POI
-curl 'https://v5.db.transport.rest/journeys?from=8010159&to.id=991561765&to.latitude=51.483641&to.longitude=11.980841' -s | jq
-# without buses, with ticket info
-curl 'https://v5.db.transport.rest/journeys?from=…&to=…&bus=false&tickets=true' -s | jq
-```
-
-

-## `GET /stations`
-
-If the `query` parameter is used, it will use [`db-stations-autocomplete@2`](https://github.com/derhuerst/db-stations-autocomplete/tree/2.2.0) to autocomplete *Deutsche Bahn*-operated stops/stations. Otherwise, it will filter the stops/stations in [`db-stations@3`](https://github.com/derhuerst/db-stations/tree/3.0.1).
-
-Instead of receiving a JSON response, you can request [newline-delimited JSON](http://ndjson.org) by sending `Accept: application/x-ndjson`.

 ## 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).
