-A flow written in ES6 using Immutable to convert between API description formats (Swagger, etc.) and other programs such as cURL command lines.
+A library written in ES6 using [Immutable.js](https://facebook.github.io/immutable-js/docs/) to convert between API description formats (including Swagger and RAML) and applications (including Paw and Postman).
 
 ## What formats are supported and what will be in the future
+
 We currently support:
-- `Swagger v2.0 (in/out)`
-- `RAML v1.0 (in/out)`
-- `Postman Collection v2.0 (in/out)`
-- `Paw v3.1 (in/out)`
+
+- Swagger v2.0 (in/out)
+- RAML v1.0 (in/out)
+- Postman Collection v2.0 (in/out)
+- Paw v3.1 (in/out)
 
 We intend to support:
-- `Swagger v3.0`
-- `RAML v0.8`
-- `Postman Collection v1.0`
-- `Postman Dump v1.0`
-- `Insomnia v3.0`
-- `Api-Blueprint`

+## User Interface
+
+API Flow is one of the main components of [Console.REST](https://github.com/luckymarmot/console-rest). If you're an API user, you can easily use [https://console.rest/](https://console.rest/) to convert API description files. If you're an API provider, you can add a button to your API docs to let your users open and play with your API in client apps including Paw or Postman.
+
+## Formats
+
+| Name | Format | Version |
+| ---- | ------ | ------- |
+| [Swagger/OAS](https://swagger.io/) | `swagger` | `v2.0` |
+| [RAML](https://raml.org/) | `raml` | `v1.0` |
+| [Paw](https://paw.cloud) | `paw` | `v3.0` |
+| [Postman Collection](https://github.com/postmanlabs/postman-collection) | `postman-collection` | `v2.0` |
+| Internal API Flow Data | `internal` | `v1.0` |
+
+## Development
+
+### Testing

 ## Contributing
 
 PRs are welcomed!
-Our sole requirement is that organizations that want to extend API-Flow to support their format write both a parser and a serializer, and not simply a serializer.
