First-step friendly
Start with connection, player identity, and the account model before moving into transactions and gameplay systems.
Developer docs for Star Atlas SAGE C4 on the z.ink testnet, shaped for first integrations, debugging, and agent-friendly lookup.

Start here
Use this site to get from zero to useful quickly: connect to the right cluster, understand the core accounts, inspect generated client calls, and review transaction effects before you ask a wallet to sign anything.
Pick a path
Learn the major programs, account relationships, and the order most integrations should understand them.
Copy the right RPC, WebSocket, explorer, and commitment settings for the z.ink testnet environment.
How to summarize signers, writable accounts, simulations, and state changes before a wallet prompt.
Reference habits
Use read-only examples to verify account layout, authority expectations, and decoded state before transaction work.
See how SAGE gameplay, player identity, faction state, and support programs fit together at the account level.
Use the glossary and workflow pages as structured context for local scripts, agents, and code generation prompts.
