+### hideIrrelevantMethods
+By default, loopback-component-jsonapi disables a number of methods from each endpoint
+that are not jsonapi relevant. These methods are:
+- upsert
+- exists
+- findOne
+- count
+- createChangeStream
+- updateAll
+You can use this option to reenable these methods.
+Please note, these methods will not be modified by the component and so their output
+will not be in a jsonapi compliant format.

 ## Debugging
 You can enable debug logging by setting an environment variable:
