# TVMLKit

Create client-server apps by incorporating JavaScript and TVML files in your binary app.

## Overview

The TVMLKit framework enables you to evaluate TVMLKit JS and TVML files from within your tvOS app. You can create TVML elements, styles, views, and view controllers through the JavaScript environment.
