# OpenAPI and Bruno

OpenAPI Specification (OAS) is a standard format for reading and describing HTTP APIs. This allows people to understand how an API works, how a sequence of APIs work together, generate client code, create tests, apply design standards, and more.

Bruno allows you to work with OpenAPI Specification (OAS) files in a number of ways:

* [Creating a collection from an OAS file import](./importOAS)
* [Exporting a collection as an OAS file](./exportOAS)
* [Viewing and Designing an OAS file](./createOAS)
