 # Example Workflow
 
-Here we demonstrate the steps to create a MultiSig transaction in Sui using CLI and then submit it using the Sui CLI against a local network. A transaction can be a transfer of an object, publish or upgrade a package, pay Sui, etc. To learn how to set up a local network, see [Sui Local Network](../build/sui-local-network.md)
