Setup Watson Natural Language Classifier and Dialog services on Bluemix

1. Setup Bluemix and Cloud Foundry

A) You need a Bluemix account. If you don't have one, sign up.

B) Bluemix use Cloud Foundry's command line tools to interact with your services from the command line. If you haven't already installed these tools, then go to the Cloud-foundry CLI tool page, scroll down to the installer section, and select the .pkg or .tgz approach.

NOTE for Mac El Capitan: The Cloud Foundry .pkg installer is buggy on El Capitan. We recommend downloading the binary instead for Mac until this issue is fixed. You may also need to run "xcode-select --install" if you recently transitioned to El Capitan.

C) Edit the manifest.yml file and change <application_name> to something unique. The name you use determines the URL of your application. For example, <application_name>.mybluemix.net.

declared-services:
  ipa-dialog_service:
    label: dialog
    plan: standard
  ipa-nlc_service:
    label: natural_language_classifier
    plan: standard
applications:
- services:
  - ipa-nlc_service
  - ipa-dialog_service
  name: <application_name>
  command: node app.js
  path: .
  memory: 128M

####2. Name Your Dialog Dialog names must be globally unique. So think of a clever dialog name and replace the <unique_dialog_name> in public/javascript/ipaRemote.js.

var IPA_DIALOG_NAME = "<unique_dialog_name>";

####3. Create the Services on Bluemix Connect to Bluemix with the command line tool as shown below. You'll be entering the text on lines beginning with the dollar sign ($).
