+## Actors overview
 
 Actors are serverless cloud programs that can perform anything from a simple action, like filling out a web form, to a complex operation, like crawling an entire website or removing duplicates from a large dataset. Because Actors can persist their state and be restarted, their runs can be as short or as long as necessary, from seconds to hours, or even indefinitely.
