If you haven't yet gone through the [actors]({{@link apify_platform/getting_started/actors.md}}) lesson of the **Apify platform** course, it's highly recommended to at least give it a glance before moving forward.

+In this course, we'll be working out of the Amazon scraper project from the **Web scraping for beginners** course. If you haven't already built that project, you can do it in three short lessons [here]({{@link web_scraping_for_beginners/challenge.md}}). We've made a few small modifications to the project with the Apify SDK, but 99% of the code is still the same.
 
 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 basically just a serverless platform that is running multiple Docker containers. For a deeper understanding of actor Dockerfiles, refer to the [Apify actor Dockerfile docs](https://sdk.apify.com/docs/guides/docker-images#example-dockerfile).
