The emulator is a lightweight tool that emulates the behaviour of the real Flow network.\n* [Visual Studio Code extension](https://github.com/onflow/vscode-cadence). The Visual Studio Code extension enables the development, deployment of, and interaction with Cadence contracts.\n\n\n\n## Documentation\n\nCheck out the [Cadence Docs](https://docs.onflow.org/cadence/language/).\n\n## Contributing\n\nIf you would like to contribute to Cadence, have a look at the [contributing guide](https://github.com/onflow/cadence/blob/master/CONTRIBUTING.md).\n\nDevelopment documentation can be found in the [`/docs` directory](https://github.com/onflow/cadence/tree/master/docs).\nFor example, it contains the source for the language reference.\n\nYou can also look out for the next [Cadence Working Group](https://github.com/onflow/Flow-Working-Groups/tree/main/cadence_language_and_execution_working_group) meeting and join our discussions!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fonflow%2Fcadence","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fonflow%2Fcadence","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fonflow%2Fcadence/lists"}
