+## Requirements
+
+Building the API client library requires [Maven](https://maven.apache.org/) to be installed.
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn deploy
+```
+
+Refer to the [official documentation](https://maven.apache.org/plugins/maven-deploy-plugin/usage.html) for more information.
+
+### Maven users
+
+Add this dependency to your project's POM:
+
+```xml
+<dependency>
+    <groupId>de.uulm.omi.cloudiator.catalogue</groupId>
+    <artifactId>client</artifactId>
+    <version>1.0.0</version>
+    <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+compile "de.uulm.omi.cloudiator.catalogue:client:1.0.0"
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+    mvn package
+
+Then manually install the following JARs:
+
+* target/client-1.0.0.jar
+* target/lib/*.jar
+
+## Getting Started
+
+Please follow the [installation](#installation) instruction and execute the following Java code:
+
+```java
+
+import de.uulm.omi.cloudiator.catalogue.client.*;
+import de.uulm.omi.cloudiator.catalogue.client.auth.*;
+import de.uulm.omi.cloudiator.catalogue.client.model.*;
+import de.uulm.omi.cloudiator.catalogue.client.api.ApplicationApi;
+
+import java.io.File;
+import java.util.*;
+
+public class ApplicationApiExample {
+
+    public static void main(String[] args) {
+        
+        ApplicationApi apiInstance = new ApplicationApi();
+        String applicationName = "applicationName_example"; // String | maps to the parent application description to identify its application components
+        java.util.List<Component> components = Arrays.asList(new Component()); // java.util.List<Component> | a list of application components
+        try {
+            CloudiatorApplicationInstance result = apiInstance.genericPost(applicationName, components);
+            System.out.println(result);
+        } catch (ApiException e) {
+            System.err.println("Exception when calling ApplicationApi#genericPost");
+            e.printStackTrace();
+        }
+    }
+}
+
+```

+## Documentation for Authorization
+
+All endpoints do not require authorization.
+Authentication schemes defined for the API:
+
+## Recommendation
+
+It's recommended to create an instance of `ApiClient` per thread in a multithreaded environment to avoid any potential issues.
