After you have created your new project you can proceed writing contracts and by running dev command the CLI will make sure they are deployed to the Flow emulator for you. Flow emulator is a simplified version of Flow network you can use locally to develop.

So proceed by starting the emulator:

Once you've established your new project, you can begin writing your own Cadence contracts. By utilizing the flow dev command, the CLI will take care of deploying them to the Flow emulator on your behalf. The Flow emulator serves as a simple version of the Flow network, enabling you to carry out local development.

Start the emulator by running:

_10

> flow emulator

And then the flow dev:

_10

> flow dev
