-# Design Patterns in TypeScript #
-
-Here are the implementations of the following design patterns in TypeScript:
-
-### Creational ###
-
-* [Singleton](https://github.com/torokmark/design_patterns_in_typescript/tree/master/singleton)
-* [Abstract Factory](https://github.com/torokmark/design_patterns_in_typescript/tree/master/abstract_factory)
-* [Factory Method](https://github.com/torokmark/design_patterns_in_typescript/tree/master/factory_method)
-* [Builder](https://github.com/torokmark/design_patterns_in_typescript/tree/master/builder)
-* [Prototype](https://github.com/torokmark/design_patterns_in_typescript/tree/master/prototype)
-
-
-### Structural Patterns ###
-
-* [Adapter](https://github.com/torokmark/design_patterns_in_typescript/tree/master/adapter)
-* [Bridge](https://github.com/torokmark/design_patterns_in_typescript/tree/master/bridge)
-* [Composite](https://github.com/torokmark/design_patterns_in_typescript/tree/master/composite)
-* [Decorator](https://github.com/torokmark/design_patterns_in_typescript/tree/master/decorator)
-* [Facade](https://github.com/torokmark/design_patterns_in_typescript/tree/master/facade)
-* [Flyweight](https://github.com/torokmark/design_patterns_in_typescript/tree/master/flyweight)
-* [Proxy](https://github.com/torokmark/design_patterns_in_typescript/tree/master/proxy)
-
-
-### Behavioral Patterns ###
-
-* [Chain of Responsibility](https://github.com/torokmark/design_patterns_in_typescript/tree/master/chain_of_responsibility)
-* [Command](https://github.com/torokmark/design_patterns_in_typescript/tree/master/command)
-* [Interpreter](https://github.com/torokmark/design_patterns_in_typescript/tree/master/interpreter)
-* [Iterator](https://github.com/torokmark/design_patterns_in_typescript/tree/master/iterator)
-* [Mediator](https://github.com/torokmark/design_patterns_in_typescript/tree/master/mediator)
-* [Memento](https://github.com/torokmark/design_patterns_in_typescript/tree/master/memento)
-* [Observer](https://github.com/torokmark/design_patterns_in_typescript/tree/master/observer)
-* [State](https://github.com/torokmark/design_patterns_in_typescript/tree/master/state)
-* [Strategy](https://github.com/torokmark/design_patterns_in_typescript/tree/master/strategy)
-* [Template Method](https://github.com/torokmark/design_patterns_in_typescript/tree/master/template_method)
-* [Visitor](https://github.com/torokmark/design_patterns_in_typescript/tree/master/visitor)
-
-## Compile the project
-
-```
-$ git clone https://github.com/torokmark/design_patterns_in_typescript.git
-$ cd design_patterns_in_typescript
-$ tsc
-```
-
-There is a new `tsconfig.json` file in the root direcotry which is responsible for the compiler options.
-As it is set the default target is Ecmascript5 now.
-Any additional options come here.
-
-To compile only one pattern, use the following command.
-
-```
-$ cd design_patterns_in_typescript/visitor
-$ tsc --target ES5 visitor.ts
-```
-> Here if there is no `--outFile` option then the compiler generates the js counterpart into the current directory.
