 You can deploy a stateless zkapp with the following command:
 
 ```shell
-$ zkbtc deploy-zkapp --circom-circuit-path examples/circuit/stateless.circom --satoshi-amount 1000

 This will lock 1,000 satoshis in the zkapp and return the transaction ID of the transaction that deployed the zkapp. A stateless zkapp can be referenced by that transaction ID.
 
 Bob can then unlock the funds from the stateless zkapp with the following command:

 ### Stateful zkapps
 
 A stateful zkapp is a zkapp that has a state, and which state can be updated without consuming the zkapp.
