Execute [`create-next-app`](https://github.com/zeit/next.js/tree/canary/packages/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
It provides an example of using `pages/_app.js` to include the context api provider and then shows how both the `pages/index.js` and `pages/about.js` can both share the same data using the context api consumer.
We start of by creating two contexts. One that actually never changes (`CounterDispatchContext`) and one that changes more often (`CounterStateContext`).
The `pages/index.js` shows how to, from the home page, increment and decrement the context data by 1 (a hard code value in the context provider itself).
