 ## Cleaning Up
 
-Because we have to define what's in the RRD upfront, you'll have to delete the `~/.temperature/temperature.rdd` if the configuration changes. Starting the server for the first time will initialise the RRD; it will create "archives" for every machine it's expecting to monitor. These are passed in as command line arguments when you start up the server (for example `kitchen`, `garage` and `bedroom`).
-
-    $ java -jar temperature-machine-2.1.jar bad.robot.temperature.server.Server kitchen garage bedroom
-
-> Don't forget to set the hostname of each machine to match. So for the above, the server might be named `kitchen` and a RRD "archive" will be created along with `garage` and `kitchen`. If a client with a hostname of `outside` connects, it won't have an archive to write data to and you won't be able to log it's temperatures.

+Because we have to define what's in the RRD upfront, you'll have to delete the `~/.temperature/temperature.rdd` if the configuration changes. Starting the server for the first time will initialise the RRD; it will create "archives" for every machine it's expecting to monitor. These are found in `~/.temperature/temperature-machine.cfg`.
 
 So, if you need to add additional machines after running the server for the first time, you'll need to do the following.
 
     `rm ~/.temperature/*`
 
-Starting the server up when the `~/temperature.rrd` already exists **doesn't** delete it.
-
+A change in the configuration after the RRD has been created will not recreate or delete it - the configuration will be ignored until the RRD is deleted and the software restarted.
