Contributing file may be out of date, or build doesn't work for linux users?

From a linux host. The build process appears to want to launch the chrome browser for karma tests, so maybe I need something for this to work?

npm install
npm run typings.

npm run build

...why does a "simple store" require a browser for testing?

Please check this against NgRx v4, and if it’s still an issue, please reopen on https://github.com/ngrx/platform. Thanks!
