-Sample UI. This UI is not meant to be extended for your AIC project,
-but to serve as an example of how to package your application in a container.
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 10.1.7.

-## Project setup
-```
-npm install
-```
+## Development server

-### Compiles and hot-reloads for development
-```
-npm run serve
-```
+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.

-### Compiles and minifies for production
-```
-npm run build
-```
+## Code scaffolding

-### Lints and fixes files
-```
-npm run lint
-```
+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`.

-### Customize configuration
-See [Configuration Reference](https://cli.vuejs.org/config/).
+## 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.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
