From clean install to your first on-chain object without getting stuck

You start by installing the Sui CLI and the Move toolchain so you can build and publish code, then you run sui client active-address to confirm a working keypair and hit the faucet to get test SUI, after which you create a fresh Move package with the template so you don’t fight folder structure, then you edit a single module to define a simple object with an owner field and a few methods like init, update, and transfer so you can exercise Sui’s object model quickly, next you compile with sui move build and fix any errors the compiler shows because that is your fastest feedback loop, then you publish with sui client publish --gas-budget and grab the package and module IDs from the output so you can call functions, after that you call your init entry function to mint an object and copy the object ID from the transaction effects, then you run sui client object to see version, owner and fields so you confirm the chain wrote what you expect, if you run into “insufficient gas” you shrink the gas budget or request more test SUI since every publish and call costs gas, if you get “module not found” you probably used the wrong package ID or forgot to rebuild, if your transfer fails with a capability error you likely made the object shared when you meant owned or you forgot to pass the correct argument shape, once the basics work you script the flow in a shell or JavaScript script so one command builds, publishes, mints, updates and transfers, which saves time and prevents typos, and finally you push this minimal example to a repo so teammates can clone and run the same steps in minutes; by treating the object as the unit of thinking rather than a single global contract you align how you code with how Sui stores state, which keeps your mental model clean and prevents hard-to-debug reentrancy or global-state races that you might meet on other chains, and because Sui parallelizes owned-object transactions you also see fast confirmation while you iterate which makes onboarding much nicer.
