 ## What is Ignition?
 
 Ignition is how you get your new project off the ground quickly and on it's way to the moon. Ignition is a starter kit application providing you with a simple and easy to use platform for creating modern React applications without having to fiddle about with configuration. It's ready to go with all the things you need: Apollo for talking to GraphQL API's and simple tooling with Webpack. The goal of Ignition is to keep things simple while providing you a great developer experience that you can easily scale into powerful applications.
