+## Bower Components
+
+The following packages are always installed by the [app](#app) generator:
+
+* angular
+* angular-cookies
+* angular-mocks
+* angular-resource
+* angular-sanitize
+* es5-shim
+* font-awesome
+* json3
+* jquery
+* lodash
+
+These packages are installed optionally depending on your configuration:
+
+* angular-route
+* angular-ui-router
+* angular-socket-io
+* angular-bootstrap
+* bootstrap
+
+All of these can be updated with `bower update` as new versions are released.
+
+## Injection
+
+A grunt/gulp task looks for new files in your `client/app` and `client/components` folder and automatically injects them in the appropriate places based on an injection block.
+
+* `less` files into `client/app/app.less`
+* `scss` files into `client/app/app.scss`
+* `stylus` files into `client/app/app.styl`
+* `css` files into `client/index.html`
+* `js` files into `client/index.html`
+* `babel`/`typescript` temp `js` files into `client/index.html`
+* `typescript types` into `tsconfig.client.json` & `tsconfig.client.test.json`
+
+
+## Configuration
+Yeoman generated projects can be further tweaked according to your needs by modifying project files appropriately.
+
+A `.yo-rc` file is generated for helping you copy configuration across projects, and to allow you to keep track of your settings. You can change this as you see fit.
+
+## Testing
+
+Running `grunt test` will run the client and server unit tests with karma and mocha.
+
+Use `grunt test:server` to only run server tests.
+
+Use `grunt test:client` to only run client tests.
+
+**Protractor tests**
+
+To setup protractor e2e tests, you must first run
+
+`npm run update-webdriver`
+
+Use `grunt test:e2e` to have protractor go through tests located in the `e2e` folder.
+
+**Code Coverage**
+
+Use `grunt test:coverage` to run mocha-istanbul and generate code coverage reports.
+
+`coverage/server` will be populated with `e2e` and `unit` folders containing the `lcov` reports.
+
+The coverage taget has 3 available options:
+- `test:coverage:unit` generate server unit test coverage
+- `test:coverage:e2e` generate server e2e test coverage
+- `test:coverage:check` combine the coverage reports and check against predefined thresholds
+
+* *when no option is given `test:coverage` runs all options in the above order*
+
+**Debugging**
+
+Use `grunt serve:debug` for a more debugging-friendly environment.
+
+## Environment Variables
+
+Keeping your app secrets and other sensitive information in source control isn't a good idea. To have grunt launch your app with specific environment variables, add them to the git ignored environment config file: `server/config/local.env.js`.
