 This will run all tests; to run only a specific subset of tests, use:
 
 ```Shell
-jake runtests tests=<regex>
+gulp runtests --tests=<regex>
 ```
 
 e.g. to run all compiler baseline tests:
 
 ```Shell
-jake runtests tests=compiler
+gulp runtests --tests=compiler
 ```
 
 or to run a specific test: `tests\cases\compiler\2dArrays.ts` 
 
 ```Shell
-jake runtests tests=2dArrays

 You will probably only want to debug one test at a time:
 
 ```Shell
-jake runtests-browser tests=2dArrays
+gulp runtests-browser --tests=2dArrays
 ```
 
 You can specify which browser to use for debugging. Currently Chrome and IE are supported:
 
 ```Shell
-jake runtests-browser tests=2dArrays browser=chrome
+gulp runtests-browser --tests=2dArrays --browser=chrome

 When a change in the baselines is detected, the test will fail. To inspect changes vs the expected baselines, use

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

 to establish the new baselines as the desired behavior. This will change the files in `tests\baselines\reference`, which should be included as part of your commit. It's important to carefully validate changes in the baselines.
