+# Overview of the APP
+
+The application consist of two parts, an API and a front end. The application displays 5 fruits which are seeded to the database at the startup. The get API provides the list of fruits. Anyone can like a fruit. In this case the count of like will be increased.
+
+![homepage](images/homepage.png?raw=true "System Architecture")
+
+# Requirements
+
+The basic system requirements are as follows
+
+- Any OS, preferably Linux
+- Docker
+- Docker compose
+
+# Architecture
+
+![Architecture](images/fruitapp.jpg?raw=true "System Architecture")
+
+### Technology used
+
+- Flask (Backend Rest API)
+- Angular (Frontend)
+- MySQL - as persistent database
+
+# Docker environment
+
+For shipping and deploying the application docker-compose is used. All the configurations are in the docker-compose.yml file.
+
+Key points of the docker-compose.yml is given below.
+
+## services
+
+- **backend:** runs the Flask web API.
+- **db** runs the mysql database required for the backend API
+- **web** this is the front-end application
+
+## Virtual networks
+
+One virtual network is used
+
+- main
+
+## list of the containers
+
+### fruitapp-backend
+
+This container runs under the service name backend. The dockerfile user for this container is located at `fruitapp-backend/Dockerfile`. This container is based on python:3.9 image.
+
+### fruitapp-frontend
+
+The frontend container for the application. The dockerfile is located at `fruitapp-frontend/.docker/dev/Dockerfile`. Base image used to build this container is `Node:14`.
+
+### db container
+
+The container is built using the official `mysql:5.7.22` image pulled from dockerhub.
+
+## Preparation
+
+To prepare the environment for the first time run the following command
+
+```shell
+bash prepare-app.sh
+```
+
+## Running
+
+Run the app background
+
+```shell
+bash start-app.sh
+```
+
+see the logs of backend
+
+```
+docker-compose logs -f backend
+```
+
+see the logs of forntend
+
+```
+docker-compose logs -f web
+```
+
+see the logs of database
+
+```
+docker-compose logs -f db
+```
+
+## Stopping
+
+```shell
+bash stop-app.sh
+```
+
+## Removing containers
+
+```shell
+bash remove-app.sh
+```
+# Viewing the app
+
+After running the app. visit [http://localhost:4200](http://localhost:4200) to view the app

+# DockerizeAngular
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 11.2.2.
+
+## 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.
+
+## 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 Overview and Command Reference](https://angular.io/cli) page.
