This is a dumb Polymer 3 preview project that I created for demo in my GDG Devfest Bangkok 2017 session that will give a taste of what Polymer 3 element will be.

1. NodeJS and npm
2. Yarn
3. Polymer CLI

1. Download it or clone it and then install dependencies with command

yarn install

2. Serve project with command

polymer serve --npm

3. Play with it. Edit element. Add more element. Whatever you want! Just Do It!
