+# Example
+
+This is an example app using `jest-preset-angular`. It is not supposed to be a boilerplate for an Angular app tested with jest, but could be used as a rough reference for configuration.
+
+The jest configuration itself is located in the `jest.config.js`.
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 12.0.0.
+
+## Running unit tests
+
+Run `yarn test` or `npm test` to execute the unit tests via [Jest](https://jestjs.io).
+
+## Running end-to-end tests
+
+End-to-end are not setup in this project.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.
