 ## Synopsis
 
 ```**sh
-$ 3DFileViewer
+$ 3DFileViewer [file]
 ```
 
 ## Description
 
 `3D File Viewer` is an application for viewing 3D models.
 
-It currently supports opening the Wavefront OBJ file format (`.obj`).
+It currently supports opening the [Wavefront OBJ file format](https://en.wikipedia.org/wiki/Wavefront_.obj_file) (`.obj`).
 
-### Features
+## Features
 
-By default 3D File Viewer will open with a rotating [Utah teapot](https://en.wikipedia.org/wiki/Utah_teapot), a standard 3D test model.
+By default, 3D File Viewer opens with a rotating [Utah teapot](https://en.wikipedia.org/wiki/Utah_teapot), a standard 3D test model. Open files via *File → Open* (`Ctrl+O`) or dragging and dropping files into the application. Sample files can be found in `Documents/3D Models`.
 
-Rotate the model by grabbing it with the cursor. Zoom-in and out with the mouse wheel.
+Orbit around the model by grabbing it with the cursor, and zoom in and out with the mouse wheel.
 
-The rotation axis and speed can be adjusted or turned off in the `View` menu.
+### View Options
 
-The model's texture can be adjusted or turned off in the `Texture` menu.
+* View in Fullscreen mode by pressing `F11` and press `Esc` to return to windowed mode.
+* **Rotation Axis** - Enable or disable rotation:
+    * **X** rotates upwards.
+    * **Y** rotates right.
+    * **Z** rotates clockwise.
+* **Rotation Speed** - Set to slow, normal, fast or disable.
+* **Show Frame Rate** - Display FPS (frames per second) and frame time values (indicating how long it took to render a single frame) in the top-right corner.
 
-View in Fullscreen by pressing `F11`.
+### Texture Options
 
-Drag and drop files into 3D File Viewer to open them.
+To load a texture, ensure there's a [Bitmap image file](https://en.wikipedia.org/wiki/BMP_file_format) (`.bmp`) with the same name as the OBJ file in the same folder and 3D File Viewer will attempt to load it automatically.
+
+* **Enable Texture** - On by default, disable for a blank (gray) model.
+* **Wrap S or T** - Controls how a texture is applied horizontally (S) or vertically (T):
+    * **Repeat** - Tiles the texture along the axis.
+    * **Mirrored** - Tiles and mirrors the texture along the axis.
+    * **Clamp** - Stretches or clamps the texture edges instead of repeating it.
+* **Scale** - Adjusts texture size (e.g. `0.5` reduces by half, `2x` doubles the size).
+* **Mag Filter** - Determines the appearance of textures when enlarged beyond their original resolution.
+    * **Nearest** - *Nearest Neighbor* means no scaling is applied to the texture, resulting in a pixellated look.
+    * **Linear** - *Linear Interpolation* scales the image by estimating pixel values, resulting in a smoother image.
+
+Currently, the flashing color lights can't be disabled.
+
+Settings persist whilst the application is open with different files, but do not persist between sessions.
+
+## Arguments
+
+* `file`: The 3D file to be viewed.
