You will most probably want to start with setting up a Zero-OS cluster, as documented in Zero-OS Orchestrator Development Setup.
This will allow you then to:
- Interact with the RESTful API exposed by the Zero-OS Orchestrator, as discussed in Zero-OS Orchestrator RESTful API
- Setup a storage cluster using the Zero-OS Orchestrator RESTful API as documented in Storage Cluster
- Test block storage, documented in Block Storage
