Make sure you are using recent versions of node and npm. No problems have been found with node>=7.10 or 6.0. and npm>=3.10.

Make sure you are using yarn>=0.23

From the command line run the following:

• yarn install (this will download all dependencies)
• yarn start (this will start the webpack development server with hot reload)
• yarn run storybook (this will start a separate webpack server for storybook, also with hot reloading)
