+## Introduction
 This repo forms part of a hands on workshop (TODO: link to slides) designed to teach [ReactJS](https://reactjs.org) and its ecosystem. Throughout the 3-day workshop, we will learn by doing: We will build a fake SPA, and will cover key concepts as we progress through the app build.
 
 The workshop starts all the way from the beginner -- with little ReactJS knowledge -- to all the way on the other side of the spectrum, covering advanced ReactJS component patterns; css-in-js using EmotionJS; predictable state management with [Redux](https://redux.js.org/); and to handling asynchronous side effects via [Redux Sagas](https://redux-saga.js.org/).
