+Majora's Mask Audio Bin Generator
+
+This script automates the creation of an MM Audio Bin file for The Legend of Zelda: Majora's Mask. With this tool, you can easily integrate custom music into the game.
+
+This script requires a decompressed ROM file of the US version of Majora's Mask to function correctly.
+
+Usage
+- Simply drag and drop your decompressed US-Majora's Mask ROM onto the script.
+- The script will generate the MM-Audio.bin file automatically.
+- Move the MM-Audio.bin file to your .../Data/Music folder.
+
+Enjoy the enhanced experience with custom music from Majoras Mask Randomizer in Ocarina of Time Randomizer!'
+
+IMPORTANT:
+For the time being i suggest not using the "Display Custom Music Names" Option, due to it showing you under circumstances the full path of the file used instead of the Cusom Music Title.
+Also given MMR Music is not "copyright issue" checked as DJ. Use at your own risk.
