-# Tomb1Main
+# Tomb Raider I: Community Edition
 
-This is a dynamic library for the classic Tomb Raider I game (TombATI version).
-The purpose of the library is to reimplement all the routines performed by the
-game and enhance the gameplay with new options.
+This is an open source implementation of the classic Tomb Raider I game. It was
+made by reverse engineering the TombATI / GLRage variant of the original game
+and replacing proprietary audio/video libraries with open source variants.
 
 See the [Tomb Raider Forums
 topic](https://www.tombraiderforums.com/showthread.php?p=8286101).
 
-This project is inspired by Arsunt's
-[TR2Main](https://github.com/Arsunt/TR2Main/) project.
+This project was inspired by Arsunt's
+[TR2Main](https://github.com/Arsunt/TR2Main/) project and the legacy name,
+"Tomb1Main", reflects that.
 
 ## Installing
 
-1. Get a copy of the latest Tomb1Main release from
-    [here](https://github.com/rr-/Tomb1Main/releases).
-2. Unpack the contents to your game directory. Make sure you overwrite existing
-    files (Tomb1Main_config.json5 can be left alone).
+1. Download the latest Tomb1Main release from the GitHub releases.  
+   https://github.com/rr-/Tomb1Main/releases
 
-To play the Unfinished Business expansion pack, launch the game with `-gold`
-command line switch:
+2. Unpack the contents to your game directory.  
+   Make sure you choose to overwrite existing directories and files
+   (`Tomb1Main_config.json5` can remain).
 
-1. Create a shortcut to `tombati.exe`
-2. Select the newly created shortcut, go to Properties
-3. At the end of the "target" field, append `-gold` so it looks something like
+3. (**Steam users / music**) The Steam version of the game does not ship with the
+   music assets due to the publishers' negligence. If you have previously
+   installed TombATI, you don't need to do anything. Otherwise you can download
+   the music files from the link below.  
+   https://mega.nz/file/f9llhQAY#y0RqaMhR4ghtQ-1IFAGbHep_FCmkV8Q66bzdMWVqtuY  
+   **These assets are not a part of this project.** The legality of these is
+   disputable. The most legal way to get the music on PC is to rip the assets
+   yourself from a physical PlayStation disk. TombATI ships with this music by
+   default, which this project chooses not to do.
+
+4. Launch `Tomb1Main.exe`.
+
+### Unfinished Business
+
+1. (**Steam users / Unfinished Business**) The Unfinished Business expansion
+   pack is freeware, however, the Steam version of the game does not ship with
+   it and you'll need to install it separately. If you have previously
+   installed TombATI, you don't need to do anything. Otherwise you can download
+   the expansion pack from the link below.  
+   https://mega.nz/file/i8s0BAaD#wy3xyhuaHnco7aJKiKUV3zO6vCe86lLa3W7hWu249-M
+
+2. Launch the game with `-gold` command line switch. A more detailed instruction:
+
+    1. Create a shortcut to `Tomb1Main.exe`.
+
+    2. Select the newly created shortcut, go to File Properties.
+
+    3. At the end of the "target" field, append `-gold` so it looks something like
         this:  
-    ```
-    (...)\tombati.exe -gold
-    ```
+        `(...)\Tomb1Main.exe -gold`
+
+    4. Launch the shortcut.

+If you install everything correctly, your game directory should look more or
