Storybook Docs w/ CRA & TypeScript

This is a quick-and-dirty walkthrough to set up a fresh project with Storybook Docs, Create React App, and TypeScript. If you're looking for a tutorial, please see Design Systems for Developers, which goes into much more depth but does not use Typescript.

The purpose of this walkthrough is a streamlined Typescript / Docs setup that works out of the box, since there are countless permutations and variables which can influence docs features, such as source code display, docgen, and props tables.

Step 1: Initialize CRA w/ TS

npx create-react-app cra-ts --template typescript
