 This Wrapper is based on the [AGHPB API](https://github.com/THEGOLDENPRO/aghpb_api/). It is a simple Java Wrapper that allows you to interact with the API in a more convenient way.
 
 ## Installation
-// TODO
+To use this Wrapper, you need to add the following repository and dependency to your `pom.xml` file.
+Replace `VERSION` with the latest version found [here](https://github.com/JoshiCodes/AGHPB4J/releases).
+
+```xml
+<repositories>
+    <repository>
+        <id>joshicodes-de-releases</id>
+        <name>JoshiCodes Repository</name>
+        <url>https://repo.joshicodes.de/releases</url>

 ## Usage
 To use the API, you first need to create a new AGHPB object. You can do this by calling the constructor and passing the URL of the API as a parameter.

 AGHPB aghpb = new AGHPB("http://localhost:5000");
 // If no url is provided, the default public api will be used (https://api.devgoldy.xyz/aghpb/v1/)
 AGHPB aghpb = new AGHPB();
-```
+```
+
+After creating the object, just use one of the available methods.
+Almost every method, returns a RestAction Object. To execute the request, you need to call the `#execute()` method.
+This method is blocking and will return the result. 
+If you want to execute the request asynchronously, you can use the `#queue()` method.
+This method will return `void`, but can take a `Consumer` as a parameter, which will be called when the request is completed.

+#### Methods
+- `AGHPB#retrieveStatus()` - `ApiStatus`
+    Returns the status of the API.
+- `AGHPB#retrieveInfo()` - `ApiInfo`
+    Returns the info of the API.
+- `AGHPB#retrieveAllCategories(boolean cache)` - `List<String>`
+    Returns a list of all available categories.
+    If `cache` is true, the result will be cached and can be returned with `AGHPB#getCategories()`.
+- `AGHPB#retrieveRandomImage(@Nullable String category, @Nullable AGHPBook.BookImageType type)` - `AGHPBook`
+    Returns a random image. Both parameters are optional and alternatively you can use the `AGHPB#retrieveRandomImage()` method without parameters or with only one parameter.
