 ### Using local builds
 
-Run `gulp build` to build a version of the compiler/language service that reflects changes you've made. You can then run `node <repo-root>/built/local/tsc.js` in place of `tsc` in your project. For example, to run `tsc --watch` from within the root of the repository on a file called `test.ts`, you can run `node ./built/local/tsc.js --watch test.ts`.

 e.g. to run all compiler baseline tests:
 
 ```Shell
-jake runtests tests=compiler

 or to run a specific test: `tests\cases\compiler\2dArrays.ts`

 You can specify which browser to use for debugging. Currently Chrome and IE are supported:

 After verifying that the changes in the baselines are correct, run
