-## Running Tests
+Run the test suite:
 
-### Runtime
-
-Some opal specific tests are found inside `spec/`, but the majority of our
-runtime tests now come from rubyspec. Rubyspec is included as a git submodule.
-To get our latest referenced checkout, just run:
-
 ```
-$ git submodule update --init
-```
-
-You need phantomjs installed to run tests. To build opal, its dependencies
-and all specs, run:
-
-```
-$ bundle exec rake mspec
-```
-
-You can alternatively run tests in a browser using:
-
-```
-$ rackup
-```
-
-And then opening `http://127.0.0.1:9292` in a web browser.
-
-### Gem/lib tests
-
-We also include some tests for running under your standard ruby implementation
-which are in `mri_spec/`. To run tests tests using rake, use:
-
-```
-$ bundle exec rake mri_spec
-```
-
-### All tests
-
-To run all the tests together (which you should do while contributing), run:
-
-```
 $ bundle exec rake
 ```
