 Image processing tasks are commented out in the gruntfile and the needed packages aren't presently in the project's `package.json`. If the images need to be processed again (minified and sprited), start by fetching the packages (`npm install grunt-contrib-imagemin grunt-sprity`), then *decomment* the tasks in `Gruntfile.coffee`. After this, the tasks can be called (explicitly, via `grunt imagemin` and `grunt sprity`).
 
+New Docker-based build process
+------------------------------
+
+Note that the Grunt workflow from above should still work, but we are transitioning to a 
+Docker based testing workflow, which is documented below:
+
+### Running the app
+
+The app runs natively using npm and Node on the local system:
+
+```
+$ npm install
+$ npm run start
+```
+
+*Ideally the app would run in Docker like the tests below, but with host networking not supported in OS X, we need to run it natively until all services are Dockerised.*
+
+### Unit Tests
+
+The test suites run in Docker.
+
+Unit tests can be run in the `test_unit` container defined in `docker-compose.tests.yml`.
+
+The makefile contains a short cut to run these:
+
+```
+make install # Only needs running once, or when npm packages are updated
+make unit_test
+```
+
+During development it is often useful to only run a subset of tests, which can be configured with arguments to the mocha CLI:
+
+```
+make unit_test MOCHA_ARGS='--grep=AuthorizationManager'
+```
+
+### Acceptance Tests
+
+Acceptance tests are run against a live service, which runs in the `acceptance_test` container defined in `docker-compose.tests.yml`.
+
+To run the tests out-of-the-box, the makefile defines:
+
+```
+make install # Only needs running once, or when npm packages are updated
+make acceptance_test
+```
+
+However, during development it is often useful to leave the service running for rapid iteration on the acceptance tests. This can be done with:
+
+```
+make acceptance_test_start_service
+make acceptance_test_run # Run as many times as needed during development
+make acceptance_test_stop_service
+```
+
+`make acceptance_test` just runs these three commands in sequence.
+
+During development it is often useful to only run a subset of tests, which can be configured with arguments to the mocha CLI:
+
+```
+make acceptance_test_run MOCHA_ARGS='--grep=AuthorizationManager'
+```
+
