+--------------
+
+`PATCH is a HTTP verb (similar to GET, POST, DELETE, PUT) to push partial changes to the REST resource. JAX-RS by default doesn't support PATCH hence Beadledom adds the support for PATCH explicitly.
+
+For more details on the PATCH method visit the PATCH RFC_.
+
+To use the PATCH method and annotation for your resource, simply annotate your JAX-RS resource method with the PATCH annotation as shown below
