+## Ridge Racer 6 Audio Extractor
+
+*RR6AudioExtractor* is a tool to extract, convert, and repackage audio from Ridge Racer 6 audio packs.
+
+### Requirements
+
+- *RR6AudioExtractor* requires that you have Java SE 17 or higher installed to run. 
+	- To install, download the latest JRE (recommended) or JDK from [Adoptium](https://adoptium.net/temurin/archive/?version=17), or JDK from [Oracle](https://www.oracle.com/java/technologies/downloads/#java17).
+
+### Usage
+
+Launch console interface
+```
+java -jar RR6AudioExtractor.java
+```
+
+Identify a file
+```
+java -jar RR6AudioExtractor.java identify <file>
+```
+
+Extract audio files from a RR6 audio pack (`BIN` → `WAV`/`XMA`)
+```
+java -jar RR6AudioExtractor.java extract <package file>
+```
+
+Convert audio files between supported formats (`WAV` ↔ `XMA` ↔ `FLAC`)
+```
+java -jar RR6AudioExtractor.java convert <audio file> <format>
+```
+
+Patch an audio file to repeat (`WAV`)
+```
+java - jar RR6AudioExtractor.java patch <audio file>
+```
+
+Pack audio files into a RR6 audio pack (`WAV`/`XMA` → `BIN`)
+```
+java -jar RR6AudioExtractor.java pack <audio directory>
+```
+
+Print a Ridge Racer 6 style ASCII logo
+```
+java -jar RR6AudioExtractor.java print <color> <text>
+``` 
+
+### About
+
+*RR6AudioExtractor* is developed by [Nes](https://gitea.goblincave.synology.me/Nes).
+
+### Referenced Libraries
+
+*RR6AudioExtractor* makes use of several Java libraries:
+- [Apache Commons Codec](https://commons.apache.org/proper/commons-codec/) v1.17.1
+- [Apache Commons CSV](https://commons.apache.org/proper/commons-csv/) v1.11.0
+- [Apache Commons IO](https://commons.apache.org/proper/commons-io/) v2.16.1
+- [javaFlacEncoder](https://javaflacencoder.sourceforge.net/) v0.3.2
+- [JColor](https://github.com/dialex/JColor) v5.5.1
+
+### Recommended Software
+
+- [*Xbox Image Browser*](https://digiex.net/threads/xbox-360-image-browser-2-9-0-350-xiso-browser-and-extractor.3136/) by Redline99
+	- For extracting and replacing files from Xbox Disc Images (`ISO`).
