 The tool can also be invoked as `python -m id_configurator`.
 
 ## Configuration format
 
+The simplest way to generate a new configuration is [InterDiode](https://interdiode.fr) itself, through its
+simple interface - it also handles duplicating application mirrors onto disconnected networks.
+
 The configuration is a JSON or YAML object. `uuid`, `organisation` and `description` are all optional
 (identifying metadata only - nothing in the tool itself relies on any of them), as is every `configurations.*`
 block - a module that finds nothing to do for it simply does not run. `version` is the configuration
