+# Overview
+
+Dusk is a reverse-engineered reimplementation of Twilight Princess.
+
+It aims to be as accurate as possible to the original while also providing new options, enhancements, and tools to customize your experience.

 # Setup
-**⚠️Dusk does NOT provide any copyrighted assets. You must provide your own copy of the game.**

-### 1. Verify your ROM dump
-First make sure your dump of the game is clean and supported by Dusk. You can do this by checking the sha1 hash of your dump against this list of supported versions.
+> [!IMPORTANT]
+> Dusk does *not* provide any copyrighted assets. You must provide your own copy of the original game.

-| Version      | sha1 hash                                |
-| ------------ | ---------------------------------------- |
-| GameCube USA | 75edd3ddff41f125d1b4ce1a40378f1b565519e7 |
