 ### Code Highlights
 
-The Direct Line API is a simple REST API for connecting directly to a single bot. This API is intended for developers writing their own client applications, web chat controls, or mobile apps that will talk to their bot. In this sample, we are using the [Direct Line Swagger file](https://docs.botframework.com/en-us/restapi/directline3/swagger.json) and [Swagger JS](https://github.com/swagger-api/swagger-js) to create a client for Node that will simplify access to the underlying REST API. Check out the client's [app.js](DirectLineClient/app.js#L7-L25) to see the client initialization.
