# Drivers

*Drivers* are an open plugin system. They provide the ability to either:

* **communicate** with external systems, hardware, or other software platforms (*device* and *service* drivers), or
* **coordinate** actions across modules and build complex behaviours (*logic* drivers).

All drivers, regardless of type, must be instantiated as [modules](/key-concepts/modules.md) before they can be used.
