 # TypeScript and JavaScript lib generator
 
-Travis CI Status: [![Build Status](https://travis-ci.org/Microsoft/TSJS-lib-generator.svg?branch=master)](https://travis-ci.org/Microsoft/TSJS-lib-generator)
+This tool is used to generate the web-based `*.d.ts` files which are included with TypeScript releases, and as `@types/x` packages.
 
-This tool is used to generate `dom.generated.d.ts`, `webworker.generated.d.ts` and `dom.iterable.generated.d.ts` for TypeScript.
-The input file is the JSON webidl file generated by the Microsoft Edge browser.
+## Why is my fancy API still not available here?
+
+A feature needs to be supported by more than two major browser engines to be included here, to make sure there is a good consensus among vendors: __Gecko__ (Firefox), __Blink__ (Chrome/Edge), and __WebKit__ (Safari).
+
+If the condition is met but still is not available here, please [file an issue](hthttps://github.com/microsoft/TypeScript-DOM-lib-generator/issues/new).
