-## Intent
-Achieve flexibility of untyped languages and keep the type-safety 
-
-![alt text](./etc/abstract-document-base.png "Abstract Document Base")
-
-![alt text](./etc/abstract-document.png "Abstract Document Traits and Domain")
-
-
-## Applicability
-Use the Abstract Document Pattern when
-
-* there is a need to add new properties on the fly
-* you want a flexible way to organize domain in tree like structure
-* you want more loosely coupled system
-

-## Intent
-Provide an interface for creating families of related or dependent
-objects without specifying their concrete classes.
-
-![alt text](./etc/abstract-factory_1.png "Abstract Factory")
-
-## Applicability
-Use the Abstract Factory pattern when
-
-* a system should be independent of how its products are created, composed and represented
-* a system should be configured with one of multiple families of products
-* a family of related product objects is designed to be used together, and you need to enforce this constraint
-* you want to provide a class library of products, and you want to reveal just their interfaces, not their implementations
-

 /**
  * 
- * The Abstract Factory pattern provides a way to encapsulate a group of individual factories that have a common theme
- * without specifying their concrete classes. In normal usage, the client software creates a concrete implementation of
- * the abstract factory and then uses the generic interface of the factory to create the concrete objects that are part
- * of the theme. The client does not know (or care) which concrete objects it gets from each of these internal
- * factories, since it uses only the generic interfaces of their products. This pattern separates the details of
- * implementation of a set of objects from their general usage and relies on object composition, as object creation is
- * implemented in methods exposed in the factory interface.
+ * The essence of the Abstract Factory pattern is a factory interface
+ * ({@link KingdomFactory}) and its implementations ({@link ElfKingdomFactory},
+ * {@link OrcKingdomFactory}).
  * <p>
- * The essence of the Abstract Factory pattern is a factory interface ({@link KingdomFactory}) and its implementations (

-## Also known as
-Wrapper
-
-## Intent
-Convert the interface of a class into another interface the clients
-expect. Adapter lets classes work together that couldn't otherwise because of
-incompatible interfaces.
-
-![alt text](./etc/adapter.png "Adapter")
-
-## Applicability
-Use the Adapter pattern when
-
-* you want to use an existing class, and its interface does not match the one you need
-* you want to create a reusable class that cooperates with unrelated or unforeseen classes, that is, classes that don't necessarily have compatible interfaces
-* you need to use several existing subclasses, but it's impractical to adapt their interface by subclassing every one. An object adapter can adapt the interface of its parent class.

-## Intent
-
-The user makes a single call to the Aggregator, and the aggregator then calls each relevant microservice and collects
-the data, apply business logic to it, and further publish is as a REST Endpoint.
-More variations of the aggregator are: 
-- Proxy Microservice Design Pattern: A different microservice is called upon the business need. 
-- Chained Microservice Design Pattern: In this case each microservice is dependent/ chained to a series 
-of other microservices.
-
-![alt text](./etc/aggregator-microservice.png "Aggregator Microservice")
-
-## Applicability
-
-Use the Aggregator Microservices pattern when you need a unified API for various microservices, regardless the client device.

-## Intent
-
-Aggregate calls to microservices in a single location: the API Gateway. The user makes a single
-call to the API Gateway, and the API Gateway then calls each relevant microservice.
-
-![alt text](./etc/api-gateway.png "API Gateway")
-
-## Applicability
-
-Use the API Gateway pattern when
-
-* you're also using the Microservices pattern and need a single point of aggregation for your
-microservice calls

-/**
- * With the Microservices pattern, a client may need data from multiple different microservices.
- * If the client called each microservice directly, that could contribute to longer load times,
- * since the client would have to make a network request for each microservice called. Moreover,
- * having the client call each microservice directly ties the client to that microservice - if the
- * internal implementations of the microservices change (for example, if two microservices are
- * combined sometime in the future) or if the location (host and port) of a microservice changes,
- * then every client that makes use of those microservices must be updated.
- *
- * <p>
- * The intent of the API Gateway pattern is to alleviate some of these issues. In the API Gateway
- * pattern, an additional entity (the API Gateway) is placed between the client and the
- * microservices. The job of the API Gateway is to aggregate the calls to the microservices.
- * Rather than the client calling each microservice individually, the client calls the API Gateway
- * a single time. The API Gateway then calls each of the microservices that the client needs.
- *
- * <p>
- * This implementation shows what the API Gateway pattern could look like for an e-commerce site.
- * The {@link ApiGateway} makes calls to the Image and Price microservices using the
- * {@link ImageClientImpl} and {@link PriceClientImpl} respectively. Customers viewing the site on a
- * desktop device can see both price information and an image of a product, so the {@link ApiGateway}
- * calls both of the microservices and aggregates the data in the {@link DesktopProduct} model.
- * However, mobile users only see price information; they do not see a product image. For mobile
- * users, the {@link ApiGateway} only retrieves price information, which it uses to populate the
- * {@link MobileProduct}.
