+The compose file defines an application with tree services  `nginx`, `front` and `backend`.
+When deploying the application, docker compose maps port 4200 of the nginx service container to port 4200 of the host as specified in the file.
+also you can access to angular app on port 4200
+and the mongoDB on port 27017
+
+
+## Deploy with docker compose
+
+```shell
+ docker compose up -d
+ [+] Running 4/0
+ ⠿ Container backend   Created                                                                             0.0s
+ ⠿ Container frontend  Created                                                                             0.0s

+ ⠿ Container nginx     Created 
+
+```
+
+## Expected result
+
+Listing containers must show three containers running and the port mapping as below:

+```
+
+## Testing the app
+
+1. After the application starts, navigate to 
+`http://localhost:4200` 
+
+
+2. Check the mongoDB connection with mongodb compass or mongo shell
+
+```
+mongosh "mongodb://localhost:27017"
+```
+
+3. Check the backend connection with postman or curl
+
+```
+curl http://localhost
+```
+
+
+## Stop and remove the containers
+
+```
+$ docker compose down
+```

+# Angular
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 13.0.1.
+
+## 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.
+
+## 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 a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
+
+## 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.
