 This template provides a good starting point to quickly play with writing, building and deploying/calling Beaker and PyTEAL contracts.
 
 This is one of the default templates used by AlgoKit to initialise an Algorand smart contract project. It's a [Copier template](https://copier.readthedocs.io/en/stable/).
