+Browser extension example using ES Modules and browser testing with Mocha,
+Chai, Sinon and Parcel for bundling.  Specifically testing in the browser to
+exercise the browser APIs available to extensions where possible.
+webextension-polyfill is used to standardize the `browser` API.
 
-Test browser APIs directly where possible and mock with Sinon otherwise.
-Sinon-chrome is available to mock chrome but ideally it would mock Firefox too.

 ```
 git clone [this repo]
 cd extension-testing-example
 npm install
-npm run build # runs parcel atm, will probably move to webpack
+npm start
 ```
 
-Then you should be able to load the `dist/` directory into your browser as an
-extension and see Fibonacci greatness.
+This should get you started developing, it will create a `dist/` directory that
+you can load into your browser as an extension if you turn on extensions
+developer mode.
+
+Parcel will also watch the source file and rebuild automatically.

+# Builds
 
-There is currently only one build but in the future only the debug build would
-include the tests so anyone can rum them after installation.

+npm run build # runs parcel build

 # Tests
 
 Click the tests button in the extension popup to run the tests in separate html
 page.
 
 You can also load the test runner using a web server rather than extension
-protocol with `npm run server` and `http://127.0.0.1:8080/test.html`.

+
+But you can't make any calls to `browser` unless you mock it because it's not
+defined, so some tests will fail.
 
 ## Integration
 
-Integration tests or e2e yet to be introduced, plan is to use webdriverio.

+Build artifacts (zip file of dist/) are being saved on CirlceCI but you might
+have to be logged into see them.  I will add them to the release page.
