+## How to get started
+
+Prism relies on the [react](https://www.npmjs.com/package/react),
+[prop-types](https://www.npmjs.com/package/prop-types),
+and [styled-components](https://www.npmjs.com/package/styled-components)
+peer-dependency packages to already be installed and set up in your project.
+
+Install prism from the npm registry by running the following command in your terminal:
+
+```bash
+npm install @ticketmaster/prism
+```
+
+Then import each component you want to use in your app:
+
+```jsx
+import React from "react";
+import ReactDOM from "react-dom";
+import { Button } from "@ticketmaster/prism";
+
+ReactDOM.render(
+  <Button variant="standard">Hello, world!</Button>,
+  document.getElementById("root")
+);
+```
+
+## How to use
+
+A documentation of each component and living styleguide is available at https://code.ticketmaster.com/prism/
