/**
* Extends the main {@link Puppeteer} class with Node specific behaviour for fetching and
* downloading browsers.
*
* If you're using Puppeteer in a Node environment, this is the class you'll get
* when you run `require('puppeteer')` (or the equivalent ES `import`).
*
* @remarks
*
* The most common method to use is {@link PuppeteerNode.launch | launch}, which
* is used to launch and connect to a new browser instance.
*
* See {@link Puppeteer | the main Puppeteer class} for methods common to all
* environments, such as {@link Puppeteer.connect}.
*
* @example
* The following is a typical example of using Puppeteer to drive automation:
* ```js
* const puppeteer = require('puppeteer');
*
* (async () => {
* const browser = await puppeteer.launch();
* const page = await browser.newPage();
* await page.goto('https://www.google.com');
* // other actions...
* await browser.close();
* })();
* ```
*
* Once you have created a `page` you have access to a large API to interact
* with the page, navigate, or find certain elements in that page.
* The {@link Page | `page` documentation} lists all the available methods.
