The Open Charging Network is a decentralized network of Electric Vehicle Charging services (OCN Parties) connected to nodes of the network (OCN Nodes). Anyone can run a node themselves, or it connect to one remotely (think OCN-as-a-Service).
To get started with the OCN, you first need to create your own OCN Identity. Please follow the steps outlined here: Creating and managing your OCN Identity
If you want to connect your own EV charging service to an OCN Node (e.g. as a Charge Point Operator or an eMobility Service Provider), please follow the steps outlined here: Connecting a service
If you want to operate your own OCN-Node, please follow the steps outlined here: Running a node
