 This tool is used to generate `dom.generated.d.ts` and `webworker.generated.d.ts` for TypeScript, and `domWeb.js` and `domWindows.js` for Visual Studio JavaScript language service. The input file is the XML spec file generated by the Microsoft Edge browser.
 
 ## Build Instruction
-**Required Software**: Visual Studio 2015 Community Version (with Visual F# installed)
-
-To build the tool, simply open the `Generator.sln` in Visual Studio and build the solution. A nuget restore should be done automatically before the build.
-
-Press `F5` in Visual Studio to run the tool. If it runs successfully, the output files will be generated under the `generated` folder.
+To build the tool, simply clone the repo, and run `build.cmd` in command line or powershell. If it runs successfully, the output files will be generated under the `generated` folder.
 
 ## Code Structure
 - `Shared.fs`: handles the parsing from XML spec file, and stores the common data structures for later use;
 - `TS.fs`: handles the emitting of the `lib.d.ts` file;
 - `JS.fs`: handles the emitting of the `domWeb.js` and `domWindows.js`
-files used for Visual Studio JavaScript language service;
-- `Program.fs`: entry point of the tool;
+
+## Contribution Guide
+The `dom.generated.d.ts` and `webworker.generated.d.ts` files that are used in TypeScript repo `master` branch are used as baselines. For each pull request, we will try run the script and compare the generated files with the baseline files. So to make the tests passed, please update the baseline and the code at the same pull request. 
 
 ## Input Files:
 - `browser.webidl.xml`: the XML spec file generated by Microsoft Edge (due to the different updating schedules between Edge and TypeScript, this may **not** be the most up-to-date version of the spec.);
