+
+The FlowFuse Assistant can now assist you by generating JSON.
+
+Wherever you edit JSON in the Rich Monaco Editor you will see the "Ask the FlowFuse Assistant 🪄" code lens.
+That includes the Inject Node, the Template Node and any contrib node that uses the built-in editor for writing JSON.
+
+We think you will find this to be a great time saver and a good helper when you are unsure of the syntax.
+
+Just ask for what you want and it does a decent job of figuring it out.
+
+Here are some examples:
+
+
+### Asking the assistant to generate JSON from within the `template` node

+### Asking the assistant to generate JSON from within the `inject` node for the `payload` value

+
+This is just the beginning of the FlowFuse Assistant's capabilities. Stay tuned!
+
+_JSON Support is available in the FlowFuse Assistant plugin starting from version 0.1.1_
