+===== Using a non-default JCache `CacheManager`
+
+If you don't want to use the default `CacheManager`, you need to set the `hibernate.javax.cache.cache_manager` configuration property
+to one of the following values:
+
+Object reference:: If the value is an Object instance implementing the `CacheManager` interface,
+the provided `CacheManager` instance will be used.
+`Class`:: If the value is a Java `Class` object that implements the `CacheManager` interface,
+Hibernate will create a new instance for that `Class` and use it instead of the default one.
++
+[NOTE]
+====
+The default no-arg constructor is going to be used, so make sure that the `CacheManager`
+implementation class provides it.
+====
+`String`:: If the value is a Java `String`, Hibernate expects it to be the fully-qualified `Class` name
+of the `CacheManager` implementation which will be used to instantiate the non-default `CacheManager`.
