Since Grav is embedded, it is instantiated as a grav.Grav object which your application code connects to in order to send and receive messages. Grav connects to other nodes via transport plugins which extend the Grav core to become a networked distributed messaging mesh. Grav instances can also discover each other automatically using discovery plugins. Grav does not require a centralized broker, and as such has some limitations, but for certain applications it is vastly simpler (and more extensible) than a centralized messaging system.
To start off, this guide will cover some concepts that are important to understand before delving into using Grav.
