Instructions on how to create an app and get Personality Insights credentials here.

Instructions on how to create an app and get Twitter credentials here(you can use more than one Twitter app ;-) ).

Start the app
```
$ node app.js
```
Update the database with the celebrities by going to:

http://localhost:3000/celebrities/syncdb

Personality Insights Credentials

The credentials for the services are stored in the VCAP_SERVICES environment variable. In order to get them you need to first create and bind the service to your application.

There are two ways to get the credentials, you can use Bluemix to access your app and view the VCAP_SERVICES there or you can run:

$ cf env <application-name>

Example output:

  System-Provided:
  {
  "VCAP_SERVICES": {
    "personality_insights": [{
        "credentials": {
          "password": "<password>",
          "url": "<url>",
          "username": "<username>"
        },
      "label": "personality_insights",
      "name": "personality-insights-service",
      "plan": "IBM Watson Personality Insights Monthly Plan"
   }]
  }
  }

You need to copy username, password.

Celebrities

The application comes with two profiles: @germanatt and @nfriedly. If you want to add more profiles you will have to:

Choose a person to include as 'celebrity'. You need at least 100 different words writted by that person, blog posts, tweets, text messages, emails will work.
Get the profile by using the Personality Insights service with the text you have and save the json profile in the profiles folder. Make sure the file has the .json extension as in the examples provided.
Start the app and go to: http://localhost:3000/celebrities/syncdb. It will repopulate the application database and add the new profile.
