 ### Prerequisites
 
-- [Node.js](https://nodejs.org) must be installed first. To use Puppeteer or Selenium WebDriver, [Chrome/Chromium](https://www.google.com/chrome/) must also be installed. It is recommended that Chrome/Chromium executable can be found through the `PATH` environment variable. Otherwise you will need to add the `--browser-executable-path` option to help SingleFile locating the executable.
-- By default SingleFile will use Puppeteer to connect to the browser. If you prefer Selenium WebDriver, you must install it first and ensure the executable can be found through the `PATH` environment variable.

Alternatively, with Selenium WebDriver, you can use [Firefox](https://www.mozilla.org/en/firefox/new/) instead. It is recommended that Chrome/Firefox binaries can be found through the `PATH` environment variable or the current folder. Otherwise you will need to set the `--browser-executable-path` option to help SingleFile locating the executable.
