-This service generates the `system.stateVersion` of the nixos installation
-automatically.
-
-Possible values:
-[system.stateVersion](https://search.nixos.org/options?channel=unstable&show=system.stateVersion&from=0&size=50&sort=relevance&type=packages&query=stateVersion)
-
-## Usage
-
-The following configuration will set `stateVersion` for all machines:
-
-```
-inventory.instances = {
-  state-version = {
-    module = {
-      name = "state-version";
-      input = "clan";
-    };
-    roles.default.tags.all = { };
-  };
-```
-
-## Migration
-
-If you are already setting `system.stateVersion`, either let the automatic
-generation happen, or trigger the generation manually for the machine. The
-service will take the specified version, if one is already supplied through the
-config.
-
-To manually generate the version for a specified machine run:
-
-```
-clan vars generate [MACHINE]
-```
-
-If the setting was already set, you can then remove `system.stateVersion` from
-your machine configuration. For new machines, just import the service as shown
-above.
