Apache Sling Resource Presence
==============================
-This module allows presentation of `Resource`s as OSGi services and comes with a simple presenter and presence.
+This module creates proxy OSGi services that are registered only if specific resources are present.
+
+Like for example:
+
+ @Reference(target="(path=/content/foo/bar)")
+ private ResourcePresence barIsPresent;
+
+The `barIsPresent` service is registered only if the `/content/foo/bar` resource is present, allowing OSGi
+components to be dependent on the presence of specific Resources.
+
+This is mostly meant for testing, to wait for test content before running specific tests.

1. Configure a service user mapping for `org.apache.sling.resource.presence` to allow reading resources, using e.g. service user `sling-readall`.
2. Configure a presenter to observe a resource by path, e.g. `path=/apps`
- Whenever resource `/apps` is available the presenter will register an OSGi service for it and unregisters the service whenever `/apps` gets removed.
-3. You can depend on that service now, e.g. using a `@Reference` annotation on your component:
