To become an operator and run a node on Walrus, you should start by visiting the official operator guide which provides step-by-step instructions on setting up your environment and running a node. The comprehensive guide is available at: https://docs.walrus.site/operator-guide/operator-guide.html. Additionally, you should have a basic understanding of operating within the Sui ecosystem because Walrus integrates with the Sui blockchain for coordination and payments.

Check out the Walrus Testnet documentation for understanding the operations of nodes, the use of tokens, and the requirements necessary to participate in the decentralized network. The Testnet acts as a testing ground before you get to the Mainnet.
