First, install Yeoman and generator-ionic-webpack-es-2015 using npm (we assume you have pre-installed node.js).
npm install -g yo
npm install -g generator-ionic-webpack
Then generate your new project:
yo ionic-webpack
Yeoman has a heart of gold. He's a person with feelings and opinions, but he's very easy to work with. If you think he's too opinionated, he can be easily convinced. Feel free to learn more about him.
