-As in all good projects, the `spec/` directory mirrors `src/` and follows the same rules. The browser runner will include and attempt to run all specs. The node runner will exclude any html-dependent specs (those in `spec/html/`).
+## Before Committing or Submitting a Pull Request
 
-You will notice that all specs are run against the built `jasmine.js` instead of the component source files. This is intentional as a way to ensure that the concatenation code is working correctly.

+1. Ensure JSHint is green with `grunt jsHint`
+1. Build `jasmine.js` with `grunt buildDistribution` and run all specs again - this ensures that your changes self-test well
 
-Please ensure all specs are green before committing or issuing a pull request.

-There are Thor tasks to help with getting green - run `thor list` to see them all. Here are the key tasks:
-
-* `thor jasmine_dev:execute_specs` outputs the expected number of specs that should be run and attempts to run in browser and Node
-* `thor jasmine_dev:execute_specs_in_browser` opens `spec/runner.html` in the default browser on MacOS. Please run this in at least Firefox and Chrome before committing
-* `thor jasmine_dev:execute_specs_in_node` runs all the Jasmine specs in Node.js - it will complain if Node is not installed
