+## GLSL Shaders
+
+FishWave includes a comprehensive GLSL shader library for video upscaling, restoration, and post-processing. All shaders work with both Vulkan and Vulkan-copy hardware decoding modes.
+
+### Shader Categories
+
+| Category | Files | Description |
+|----------|-------|-------------|
+| **FSRCNNX** | 6 | CNN-based upscaling (x1, x2 variants) |
+| **ArtCNN** | 2 | CNN upscalers (C4F16, C4F32) |
+| **RAVU** | 15 | Sharp upscaling hooks (r2, r3, r4 variants) |
+| **AMD FSR** | 2 | FidelityFX Super Resolution |
+| **Anime4K** | 3 | Anime restoration and enhancement |
+| **HDR Tone Mapping** | 15+ | PQ/HLG to SDR conversion |
+| **Misc** | 10+ | Adaptive sharpen, CRT filters, noise |
+
+### Activating Shaders
+
+**Via Context Menu (Recommended):**
+1. Right-click the video area
+2. Navigate to `Shaders` menu
+3. Select a preset (`Default`, `AMD FSR`, `RAVU Zoom R3`) or individual shader
+
+**Via Keyboard Shortcuts:**
+- `Alt+Shift+1` through `Alt+Shift+6` - Toggle individual scalers
+- `Alt+Shift+A` - Adaptive sharpen
+- `Alt+Shift+C` - CRT filter
+
+**Via Profiles:**
+- `Video > Renderer > Vulkan` - Enables Vulkan mode (required for optimal shader performance)
+- `Shaders > Presets` - Apply predefined shader combinations
+
+**Via Command Line:**
+```bash
+# Apply shader preset
+mpv --glsl-shader=~~/shaders/FSRCNNX/FSRCNNX_x2.glsl video.mp4
+
+# Apply multiple shaders
+mpv --glsl-shader=~~/shaders/FSRCNNX/FSRCNNX_x2.glsl --glsl-shader=~~/shaders/Misc/adaptive-sharpen.glsl video.mp4
+```
+
+### Status
+
+All GLSL shaders are fully functional with Vulkan and Vulkan-copy modes. mpv's `gpu-next` renderer automatically compiles GLSL to SPIR-V at runtime, ensuring optimal performance on Vulkan-capable hardware.
+
 ## Known Notes
 
 - YouTube or web URL playback depends on the bundled/configured YTDL path and can fail under VPNs or when upstream site behavior changes.
 - Some LibreHardwareMonitor sensors may be missing without driver support or elevated access.
 - The native context menu depends on `portable_config/scripts/menu.dll` and `dyn_menu.lua`.
 
-## Status
+## Project Status
 
 FishWave 9 is an active experimental player. The core playback path is usable, and the current focus is making the hardware pipeline more transparent, stable, and easy to tune.
