How do you set up Selenium 4 in a project?

Install the Selenium library Python:

pip install selenium

Or for Java:

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.x.x</version>
</dependency>

Download browser drivers (e.g., ChromeDriver, GeckoDriver).
