To test the bot locally, you will need to uncomment the config import in index.js. You will also need a config.js file at the root the directory, using the following template :
module.exports = {
consumer_key: 'XXX',
consumer_secret: 'XXX',
access_token: 'XXX',
access_token_secret: 'XXX'
}
Fill in each section with your own keys/tokens (the last four are for the Twitter API). For more information on the Twitter API, visit https://apps.twitter.com/app/new
