 Take another look at the files within your Amazon scraper project. You'll notice that there is a **Dockerfile**. Every single Actor has a Dockerfile (the Actor's **Image**) which tells Docker how to spin up a container on the Apify platform which can successfully run the Actor's code. "Apify Actors" is a serverless platform that runs multiple Docker containers. For a deeper understanding of Actor Dockerfiles, refer to the [Apify Actor Dockerfile docs](/sdk/js/docs/guides/docker-images#example-dockerfile).

 Because proxies are so widely used in the scraping world, Crawlee has built-in features for implementing them in an effective way. One of the main functionalities that comes baked into Crawlee is proxy rotation, which is when each request is sent through a different proxy from a proxy pool.

 Notice that in the Playwright example, we are using a different selector than in the Puppeteer example. This is because Playwright supports [many custom CSS selectors](https://playwright.dev/docs/other-locators#css-elements-matching-one-of-the-conditions), such as the **has-text** pseudo class. As a rule of thumb, using text selectors is much more preferable to using regular selectors, as they are much less likely to break. If Google makes the sibling above the **Accept all** button a `<div>` element instead of a `<button>` element, our `button + button` selector will break. However, the button will always have the text **Accept all**; therefore, `button:has-text("Accept all")` is more reliable.
