# Extending your contract

We've prepared a sample smart contract that tries to cover all of the basic-to-medium topics and constructs that you might need when working on your own idea - see [Bulletin Board example contract.](https://github.com/Cardinal-Cryptography/bulletin-board-example/tree/main/contracts)

Use the `README.md` of the contract as the starting point.\

Happy hacking!
