 4\. Finally, run the docker image to fetch flats and serve the web UI:
 
 ```
-docker run -P -v $FLATISFY_VOLUME:/flatisfy -p 8080:8080 phyks/flatisfy
+docker run -it -v $FLATISFY_VOLUME:/flatisfy -p 8080:8080 phyks/flatisfy
 ```
 
 Your Flatisfy instance is now available at `localhost:8080`!

+To fetch new housing posts, you should manually call
+
+```
+docker run -it -v $FLATISFY_VOLUME:/flatisfy phyks/flatisfy /home/user/fetch.sh
+```

+This can be done easily in a crontask on your host system, to run it typically
+every night.
