+## Configuration
+Kubernetes config and binary file locations and names can vary from installation to installation, so these are configurable in the `cfg/config.yaml` file. 
+
+They also tend to vary according to which tool was used to install Kubernetes. You can use the `--installation` flag to pick up a different default set of file names and locations. Again these defaults are configurable through `cfg/config.yaml` (and pull requests to correct or add default file locations are especially welcome).

 ## Test config YAML representation
 The tests are represented as YAML documents (installed by default into ./cfg).
