+# Assistant and Tone Analyzer Integration Example
+
+This example provides sample code for integrating [Tone Analyzer][tone_analyzer] and [Assistant][assistant].
+
+  * [tone_detection.js][tone_assistant_integration_example_tone_detection] - sample code to initialize a user object in the assistant payload's context (initUser), to call Tone Analyzer to retrieve tone for a user's input (invokeToneAsync), and to update tone in the user object in the assistant payload's context (updateUserTone).
+
+  * [tone_assistant_integration.v1.js][tone_assistant_integration_example] - sample code to use tone_detection.js to get and add tone to the payload and send a request to the Assistant Service's message endpoint.
+
+
+Requirements to run the sample code
+
+  * [Tone Analyzer Service credentials][bluemix_tone_analyzer_service]
+  * [Assistant Service credentials][bluemix_assistant_service]
+  * [Assistant Workspace ID][assistant_simple_workspace]
+
+Credentials & the Workspace ID can be set in environment properties, a .env file, or directly in the code.
+
+
+Command to run the sample code
+
+`npm install # just once, to download dependencies`
+`node tone_assistant_integration.v1.js`
