Adding React to a website.

React can be added to a website without any special tools or installations.

First, we add React library as two script tags to the head of the HTML document.

<script src="https://unpkg.com/react@16/umd
/react.development.js" cross origin

Next, we need add another script to enable the use of JSX.
JSX is a syntax extension to JavaScript, and it is recommended to be used with React.

<script src="https://unpkg.com/babel-standalone@6/babel.min.js">></script>

After adding the required script tags, we can start building our React app!

We add a container, that will be used to display something using React.

<div id="container"></div>

You can use any *id * for your container. React will use it to find container and add content to it.
