$ npm install
Make a copy of the sample config:
$ cp conf/conf.js.sample conf/conf.js

View the app in a browser . Navigate to /admin/setup to begin the setup process.
Step 1: Create a user name and password.
Step 2: Configure Twitter App keys .
Step 3: Connect your Twitter account.

 Ignore the sidebar that shows up when you're not logged in. Log in first and then use it.
 If you plan to use the provided Twitter API keys/tokens, you MUST use "local.saturn.io:3000" (set local.saturn.io -> 127.0.0.1 in hosts). If you set up a new dev app on Twitter, you can set the callback URL/domain to anything you want, including localhost, 127.0.0.1, etc.
