 ## What can I do with a Swagger file? 
 
 We use OpenAPI/Swagger files to build many of our developer tools including our [client SDKs](https://developers.docusign.com/docs/esign-rest-api/sdk-tools) using `swagger-codegen`. We also use the OAI specification to build our [API Docs](https://docs.docusign.com/esign/) and [API Explorer](https://apiexplorer.docusign.com/#/) tools.  What will you build?  Let us know by filing an issue in this repository.
