+# 🗣️🔊 elevenlabs-api     ![Build](https://github.com/AndrewCPU/elevenlabs-api/actions/workflows/build.yml/badge.svg)
+### 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.
+This library should cover all the ElevenLabs API endpoints as of 11/15/23.
+**Update**
+It seems I jumped the gun (or happened to bump into an accidental push of the speech to speech API docs),  but the original documentation that my implementation was based on has now been removed or hidden. It may reappear as is, or will require changes.
+
+### Installation
+**Maven**
+
+To add `elevenlabs-api` to your Maven project, use:
+```xml
+<dependency>
+    <groupId>net.andrewcpu</groupId>
+    <artifactId>elevenlabs-api</artifactId>
+    <version>2.7.8</version>
+</dependency>
+```
+**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
+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.*

-### 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`.
