You are the Never Sea Festival 2023 organizers and you decide to create the registration via blockchain.
Starting from Smart Contract template you have to add more features to coordinate the event.

to provide the arguments of init function.
Check the deployment on the explorer. Do not assume that the contract was successfully deployed if there are no command line errors.
erdpy contract deploy –help
To check that the contract was successfully built, verify that there was a wasm file generate: output/neversea.wasm
.
This is the compiled code of your contract.
To check that the contract was successfully deployed, check the devnet/testnet.
Any modification of the contract must be succeeded by a compilation and deployment!
