## Quick Usage Instructions

1. Anime4K has 3 major modes: A, B, and C. Each mode is optimized for a different class of anime degradations.
    - Mode A is automatically enabled, if you use our template (this can be change in `mpv.conf`).

2. To enable each mode manually:
    - Press **CTRL+1** to enable Mode A (Optimized for 1080p Anime).
    - Press **CTRL+2** to enable Mode B (Optimized for 720p Anime).
    - Press **CTRL+3** to enable Mode C (Optimized for 480p Anime).
    - Press **CTRL+0** to clear all shaders (Disable Anime4K).
