 This plugin adds functionality to the [Twilio CLI](https://github.com/twilio/twilio-cli) to upload and manage assets to a Twilio Assets service. It's a part of the [Serverless Toolkit](https://github.com/twilio-labs/serverless-toolkit) and uses the [Serverless API](https://github.com/twilio-labs/serverless-toolkit/tree/main/packages/serverless-api).
 
+The plugin creates a new Runtime Service which it then uses as a bucket to which it upload assets. You can upload new files or list your available assets.
