Every Actor must have a Dockerfile, as Actors run in Docker containers. Place the Dockerfile in the `.actor` directory alongside your `actor.json` file.

-Though writing an [input schema](/platform/actors/development/actor-definition/input-schema) for an Actor is not a required step, it's definitely an ideal one. The Apify platform will read the `INPUT_SCHEMA.json` file within the root of your project and generate a user interface for entering input into your Actor, which makes it significantly easier for non-developers (and even developers) to configure and understand the inputs your Actor can receive. Because of this, we'll be writing an input schema for our example Actor.
