 # gns3-web-ui
-WebUI implementation for GNS3
+
+Test WebUI implementation for GNS3. 
+
+This is not production ready version. It has been made to evaluate possibility of creation Web User Interface for GNS3 application.
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 1.2.6.
+
+## Installation for development
+
+Please install `npm` if not present in your system. 
+
+Next step is `angular-cli` installation:
+
+```
+npm install @angular/cli
+```
+
+## Development server
+
+### Run GNS3 server
+
+Please run locally GNS3 server.
+
+### Using default CORS policy.
+
+GNS3 server contains CORS policies to run Web UI on 8080 at localhost. In order to use it, please run development server with custom port:
+
+```
+ng serve --port 8080
+``` 
+
+Application is accessible on `http://localhost:8080/`. 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|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/).
+Before running the tests make sure you are serving the app via `ng serve`.
+
+## Further help
+
+If you want to contribute to GNS3 Web UI feel free to reach us at `developers@gns3.net`.
