+[![Build Status](https://travis-ci.org/watson-developer-cloud/assistant-demo.svg?branch=master)](https://travis-ci.org/watson-developer-cloud/assistant-demo)
+
+In this sample application, you're engaging with a banking virtual assistant. The assistant simulates a few scenarios, such as making a credit card payment, booking an appointment with a banker and choosing a credit card. Watson can understand your entries and respond accordingly.
+
+
+[![Demo](./demo.gif)](https://watson-assistant-demo.ng.bluemix.net)
+
+
+
+## Prerequisites
+
+1. Sign up for an [IBM Cloud account](https://cloud.ibm.com/registration).
+1. Download the [IBM Cloud CLI](https://cloud.ibm.com/docs/cli/index.html#overview).
+1. Create an instance of the Watson Assistant service and get your credentials:
+    - Go to the [Watson Assistant][service_url] page in the IBM Cloud Catalog.
+    - Log in to your IBM Cloud account.
+    - Click **Create**.
+    - Click **Show** to view the service credentials.
+    - Copy the `apikey` value.
+    - Copy the `url` value.
+
+## Configuring the application
+
+1. In the application folder, copy the *.env.example* file and create a file called *.env*
+
+    ```
+    cp .env.example .env
+    ```
+
+2. Open the *.env* file and add the service credentials that you obtained in the previous step.
+
+    Example *.env* file that configures the `apikey` and `url` for a Watson Assistant service instance hosted in the US East region:
+
+    ```
+    ASSISTANT_IAM_APIKEY=X4rbi8vwZmKpXfowaS3GAsA7vdy17Qh7km5D6EzKLHL2
+    ASSISTANT_URL=https://gateway-wdc.watsonplatform.net/assistant/api
+    ```
+
+## Running locally
+
+1. Install the dependencies
+
+    ```
+    npm install
+    ```
+
+1. Run the application
+
+    ```
+    npm start
+    ```
+
+1. View the application in a browser at `localhost:3000`
+
+## Deploying to IBM Cloud as a Cloud Foundry Application
+
+1. Login to IBM Cloud with the [IBM Cloud CLI](https://cloud.ibm.com/docs/cli/index.html#overview)
+
+    ```
+    ibmcloud login
+    ```
+
+1. Target a Cloud Foundry organization and space.
+
+    ```
+    ibmcloud target --cf
+    ```
+
+1. Edit the *manifest.yml* file. Change the **name** field to something unique.  
+  For example, `- name: my-app-name`.
+1. Deploy the application
+
+    ```
+    ibmcloud app push
+    ```
+
+1. View the application online at the app URL.  
+For example: https://my-app-name.mybluemix.net
+
