-A service not going to be overridden/exposed as API to other plugins does not need to be registered in <path>[plugin.xml](plugin_configuration_file.md)</path> (see [](#declaring-a-service)).
-Instead, annotate service class with [`@Service`](%gh-ic%/platform/core-api/src/com/intellij/openapi/components/Service.java) (see [](#examples)).

+* None of these attributes/restrictions (available for [registration of non-light services](#declaring-a-service)) is allowed: `id`, `os`, `client`, `overrides`, `configurationSchemaKey`/`preload` (Internal API).
+* There is no separate headless/test implementation required.
 * Service class must be `final`.
 * [Constructor injection](#ctor) of dependency services is not supported.
-* If application-level service is a [PersistentStateComponent](persisting_state_of_components.md), roaming must be disabled (`roamingType = RoamingType.DISABLED`).

+
+To expose a service's API, create a separate class for `serviceInterface` and extend it in the corresponding class registered in `serviceImplementation`.
+If `serviceInterface` isn't specified, it is supposed to have the same value as `serviceImplementation`.
 Use inspection <control>Plugin DevKit | Plugin descriptor | Plugin.xml extension registration</control> to highlight redundant `serviceInterface` declarations.
 
-To provide a custom implementation for test/headless environment, specify `testServiceImplementation`/`headlessImplementation` additionally.
+### Additional Attributes
 
-### Example
+A service can be restricted to a certain OS via the `os` attribute.
 
+To provide a custom implementation for test or headless environment, specify `testServiceImplementation` or `headlessImplementation` respectively.
