In the root folder of the project (/tau-introduction-to-playwright), there is a ".env.example" file, you can copy or rename this to just ".env" then put in your applitools API key (once you've registered on applitools.com for a free account then click on the user icon in the upper right corner then select "Your API key" from the drop down menu)

@pkunarap this is explained in chapter 2

you need this in your playwright.config

/**
 * Read environment variables from file.
 * https://github.com/motdotla/dotenv
 */
require('dotenv').config();

and you need to make sure you have dotenv installed and your package.json includes

"devDependencies": {
    "dotenv": "^16.0.3"
  }
