 - Exclude the [`src/wallabyTest.ts` file in the `tsconfig.json`](https://github.com/wallabyjs/ngCliWebpackSample/blob/82d4f43d1a1e701de403a2cdb38986bfb4ddca0b/src/tsconfig.app.json#L20) as it may affect [Angular 2 AOT compilation](https://github.com/angular/angular/issues/13624#issuecomment-281919940).
 - Run `npm install wallaby-webpack angular2-template-loader electron --save-dev`.
 
-Note that the sample is [using Chrome/Electron test runner](https://wallabyjs.com/docs/integration/electron.html), and not the wallaby.js default PhantomJs test runner. You may use PhantomJs runner if you like, to do that you may just [remove the `env` setting](https://github.com/wallabyjs/ngCliWebpackSample/blob/88a13b2c25f8808f733ec7cb058544f887f40190/wallaby.js#L49). In this case, you will not need to `npm i electron`, however will need to uncomment [core-js polyfills](https://github.com/wallabyjs/ngCliWebpackSample/blob/88a13b2c25f8808f733ec7cb058544f887f40190/src/polyfills.ts#L22) and [`Intl` polyfill](https://github.com/wallabyjs/ngCliWebpackSample/blob/88a13b2c25f8808f733ec7cb058544f887f40190/src/polyfills.ts#L68), so that PhantomJs may work.
