+## Building & Tests
+
+`npm run build` to build the project.
+
+`npm run test` to run tests.
+
+`npm run test-threaded` runs test in parallel, faster but less detailed output.
+
+`npm run coverage` or `npm run coverage-html` to generate a coverage report.
+
 ## Sublime Text integration
 This compiler works great in combination with the [Sublime Text Typescript plugin](https://github.com/Microsoft/TypeScript-Sublime-Plugin) (available through the package manager as `TypeScript`).
