+# ZipConnect
+This application was generated using JHipster 5.7.0, you can find documentation and help at [https://www.jhipster.tech/documentation-archive/v5.7.0](https://www.jhipster.tech/documentation-archive/v5.7.0).
+
+## Development
+
+To start your application in the dev profile, simply run:
+
+    
+
+
+For further instructions on how to develop with JHipster, have a look at [Using JHipster in development][].
+
+### Using angular-cli
+
+You can also use [Angular CLI][] to generate some custom client code.
+
+For example, the following command:
+
+    ng generate component my-component
+
+will generate few files:
+
+    create src/main/webapp/app/my-component/my-component.component.html
+    create src/main/webapp/app/my-component/my-component.component.ts
+    update src/main/webapp/app/app.module.ts
+
+
+## Building for production
+
+To optimize the ZipConnect application for production, run:
+
+
+To ensure everything worked, run:
+
+
+
+Refer to [Using JHipster in production][] for more details.
+
+## Testing
+
+To launch your application's tests, run:
+
+    ./gradlew test
+
+For more information, refer to the [Running tests page][].
+
+### Code quality
+
+Sonar is used to analyse code quality. You can start a local Sonar server (accessible on http://localhost:9001) with:
+
+```
+docker-compose -f src/main/docker/sonar.yml up -d
+```
+
+Then, run a Sonar analysis:
+
+```
+./gradlew -Pprod clean test sonarqube
+```
+
+For more information, refer to the [Code quality page][].
+
+## Using Docker to simplify development (optional)
+
+You can use Docker to improve your JHipster development experience. A number of docker-compose configuration are available in the [src/main/docker](src/main/docker) folder to launch required third party services.
+
+For example, to start a  database in a docker container, run:
+
+    docker-compose -f src/main/docker/.yml up -d
+
+To stop it and remove the container, run:
+
+    docker-compose -f src/main/docker/.yml down
+
+You can also fully dockerize your application and all the services that it depends on.
+To achieve this, first build a docker image of your app by running:
+
+    
+
+Then run:
+
+    docker-compose -f src/main/docker/app.yml up -d
+
+For more information refer to [Using Docker and Docker-Compose][], this page also contains information on the docker-compose sub-generator (`jhipster docker-compose`), which is able to generate docker configurations for one or several JHipster applications.
+
+## Continuous Integration (optional)
+
+To configure CI for your project, run the ci-cd sub-generator (`jhipster ci-cd`), this will let you generate configuration files for a number of Continuous Integration systems. Consult the [Setting up Continuous Integration][] page for more information.
