Contributing quickstart

Assuming git, Vagrant and VirtualBox installed:

 host$ git clone
 host$ cd snowplow-javascript-tracker
 host$ vagrant up && vagrant ssh
guest$ cd /vagrant
guest$ sudo npm install
guest$ cd core
guest$ sudo npm install

Set up an ./aws.json file using the example ./aws.sample.json. If you just want to concat + minify without uploading then you don't need to fill out the aws.json file with valid credentials.

Build the package (default task concatenates and minifies) using grunt.
