     - This will parse select few game files into `output/parsed/` directory
+    - Directions on how to opened parsed files are available [here](#file-formats-and-extraction)
+
+## Roadmap
+
+### File formats and extraction
+
+- [x] Gamma table
+    - **Purpose**
+        - Look up table for brightness when changing gamma in settings
+    - **Output format**
+        - PPM image
+- [x] Color map
+    - **Purpose**
+        - Look up table for 12-bit RGB colors, because textures are stored in 256 indexed color format
+        - There is also ghost version for when you use Ghost Vision Goggles in game
+        - There are unique color maps for monsters, pick-ups (and some other models), UI sprites, and levels
+    - **Output format**
+        - PPM image
+- [x] Model
+    - **Purpose**
+        - Texture, geometry, and model data
+    - **TO DO**
+        - Figure out what to do with pre-calculated face and vertex normals
+    - **Output format**
+        - Blender Python script that can be executed with
+            ```sh
+            blender -P /path/to/script.py
+            ```
+        - Automatically sets up Cycles material and animations as shape keys in dope sheet's shape key editor
+- [x] Sky
+    - **Purpose**
+        - Color map and skybox texture
+    - **Output format**
+        - PPM image
+- [ ] Skins
+- [ ] Level geometry
+- [ ] Level collision
+- [ ] Level waypoints
+- [ ] Sprite
+- [x] Texture
+    - **Purpose**
+        - Texture info - offsets, texture dimensions
+        - Texture data - color indeces
+    - **TO DO**
+        - Re-integrate output
+    - **Output format**
+        - PPM image
+- [x] String table
+    - **Purpose**
+        - Printable strings in UI
+    - **TO DO**
+        - Figure out weird non-text characters (probably for controlling in-game events)
+    - **Output format**
+        - Plain text
 
 ## File structure
 
 > [!IMPORTANT]

 > I use the packfile that comes with Ashen 1.06.
-> Your packfile may have different offsets to files, I didn't test with different versions.
