 ### An unofficial ElevenLabs AI Voice Generation Java API
 
 ## Getting Started
 So you wanna make custom voices, huh? Well you've come to the right place.
 
+### Note: This repo is undergoing an upgrade to v2.0
+If any of the documentation is out of place or issues occur, please submit a PR or create an issue.
+I downgraded the repo from JDK 17 to JDK 11 as well.
+
 ### Installation
 **Maven**
 
 To add `elevenlabs-api` to your Maven project, use:
 ```xml
-    <dependencies>
+<dependency>
-        ...
+    <groupId>net.andrewcpu</groupId>
-        <dependency>
+    <artifactId>elevenlabs-api</artifactId>
-            <groupId>net.andrewcpu.elevenlabs</groupId>
+    <version>2.7.2</version>
-            <artifactId>elevenlabs-api</artifactId>
+</dependency>
-            <version>CURRENT_VERSION</version>
-        </dependency>
-        ...
-    </dependencies>
 ```
+The most up-to date package information can be found on the [Packages tab](https://github.com/AndrewCPU/elevenlabs-api/packages/)
+
 
 **JAR**
 
 Compiled JARs are available via the [Releases tab](https://github.com/AndrewCPU/elevenlabs-api/releases)

 ### Setting up your API Key
 To access your ElevenLabs API key, head to the [official website](https://elevenlabs.io/), you can view your `xi-api-key` using the 'Profile' tab on the website.
 To set up your ElevenLabs API key, you must register it with the ElevenLabsAPI Java API like below:
 ```java
-ElevenLabsAPI.getInstance().setAPIKey("YOUR_API_KEY_HERE");
+ElevenLabs.setApiKey("YOUR_API_KEY_HERE");
+
+
+ElevenLabs.setDefaultModel("eleven_monolingual_v1"); // Optional, defaults to: "eleven_monolingual_v1"
 ```
 *For any public repository security, you should store your API key in an environment variable, or external from your source code.*
 
-Once you've injected your API Key, you can safely assume that you will not receive a `ElevenLabsAPINotInitiatedException`.

-### Generating Audio
+### Generating Audio (TTS + STS)
 To generate an audio file with a given `Voice`, you can utilize the `Voice#generate(...)` functions.
 Depending on how you access your `Voice`, (with or without settings), will decide whether you can use the implicit `voiceSettings` or if you have to specify the `VoiceSettings` object to use. Unless explicitly requesting the `Voice` without settings, every `Voice` object SHOULD contain its default `VoiceSettings`.
 ```java
+
 Voice voice;
-File outputFile = voice.generate(String text, VoiceSettings voiceSettings, File output);
+
-File outputFile = voice.generate(String text, File output); // Uses default voice settings
+File file = voice.generate("Hello world!", "my_favorite_model");
+...
+//Available Functions:
+public File generate(String text, String model);
+
+public File generate(String text, String model, VoiceSettings settings);
+
+public File generate(String text, String model, VoiceSettings settings, GeneratedAudioOutputFormat outputFormat, StreamLatencyOptimization streamLatencyOptimization);

 #### Unit Testing

+Unit tests have been created, these endpoints are destructive and not included in the testing:
+* deleteHistoryItem - WONT TEST
+* deleteSample - WONT TEST

+* editVoiceSettings - WONT TEST
+* createVoice - WONT TEST
+* editVoice - WONT TEST
+
+To run the unit tests yourself, you have to clone this repo and update the ElevenLabsTest.java file with your API key and your voice to test on.
