+## Spring Cloud Bootstrap
+
+This module contains articles about bootstrapping Spring Cloud applications
+
+### Relevant Articles:
+- [Spring Cloud – Bootstrapping](http://www.baeldung.com/spring-cloud-bootstrapping)
+- [Spring Cloud – Securing Services](http://www.baeldung.com/spring-cloud-securing-services)
+- [Spring Cloud – Tracing Services with Zipkin](http://www.baeldung.com/tracing-services-with-zipkin)
+- [Spring Cloud Series – The Gateway Pattern](http://www.baeldung.com/spring-cloud-gateway-pattern)
+- [Spring Cloud – Adding Angular 4](http://www.baeldung.com/spring-cloud-angular)
+
+### Running the Project
+
+- To run the project:
+  - copy the appliction-config folder to c:\Users\{username}\ on Windows or /home/{username}/ on *nix. Then open a git bash terminal in application-config and run:
+    - git init
+    - git add .
+    - git commit -m "First commit"
+  - start the config server
+  - start the discovery server
+  - start all the other servers in any order (gateway, svc-book, svc-rating, zipkin)

+# Ui
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 1.0.0.
+
+## 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/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
+
+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).
