 ## Usage

 ### Requirement
-- Java 8
-- As this project is using [gradle](https://gradle.org/), you need a plugin to import it into your IDE. [IntelliJ](https://www.jetbrains.com/idea/) does support this by default, when using [Eclipse](https://eclipse.org/) we recommend using the [Buildship Plugin](http://marketplace.eclipse.org/content/buildship-gradle-integration).

 ### Project structure
-This project consists of two modules, named client and runner. 
 
-The client module contains POJO-classes and all classes necessary to send requests to FACT-Finder via its JSON based REST API. Most of the module has been 
-generated using [swagger codegen](http://swagger.io/docs/swagger-tools/). Only the class `de.factfinder.client.UpdatingAuthKeyClient` was added manually to ensure the validity
- of the auth key for each service call. Some dependencies were also added to the generated `build.gradle`. These dependencies are needed by the manually 
- created classes.
+This project consists of two modules, named client and runner.
 
-The second module, named runner, contains example classes using that client classes. Each `Runner*`-class is executable on it's own and demonstrates a different FACT-Finder functionality.

 #### `Settings`-class
-Before you are able to run one of the `Runner*`-classes, you need to adjust the `de.factfinder.runner.Settings`-class according to the path and credentials of your FACT-Finder environment.
