Actors can be private or public. Private actors can only be accessed and started by their owner, while public actor are shown in the store and can be run by anyone. Each public actor has a globally unique identifier that consists of the owner's username and the actor name, e.g. apify/hello-world.

To publish your actor, go to Settings → Permissions on the actor detail page and click the Publish button. You'll need to have a username set. This can be done on the Profile page.

The short actor description shown in the store is taken from Settings → Description. Additionally, if the actor's source code is hosted in a Git repository, Zip file or GitHub Gist, you can add a long description in Markdown language to the or README files in the root of the source code directory. To see an example of how this looks, go to apify/web-scraper.

IMPORTANT: Note that if your actor is public and used by other people, its usage is not charged towards your account. The user running the actor is always the one who pays for the computational resources consumed by an actor's execution.
