 # Chroma
 
-A simple, lightweight and efficientt wallpaper daeemon for Wayland compositors
-with multi-monitor & automatic hotplugging support. Born from my woes with
-Hyprpaper, swaybg and most ironically SWWW, which turned out to be NOT a
-solution to my Wayland wallpaper woes.
+Super-fast, lightweight and efficient wallpaper daemon for Wayland compositors
+with multi-monitor & hotplugging support. Born from my woes with Hyprpaper,
+swaybg and most ironically _SWWW_ (now called AWWW for some awful reason), which
+turned out to be NOT a solution to my Wayland wallpaper woes. Smaller, faster,
+cleaner and somehow still more feature-rich...
 
 ## Features
 
-I did not expect to be writing something too feature-rich, but I still ended up
-with something relatively convoluted. Chroma (mostly) reliably supports:
+Chroma combines simplicity with powerful performance optimizations and
+comprehensive monitor management. Here's what makes Chroma stand out:
 
-- **Multi-monitors**: Automatically detects and manages wallpapers for all
-  connected displays
+### Core Functionality
+
+- **Memory-efficient**: Smart caching and resource management
+  - **Optimized rendering**: VBO dirty flagging and reduced GPU overhead
+- **Multi-monitor support**: Automatically detects and manages wallpapers for
+  all connected displays
+  - **Configurable scaling modes**: Fill, fit, stretch, and center options per
+    monitor
 - **Hotplugging**: Dynamically handles monitor connection/disconnection events
-- **Per-output configuration**: Set different wallpapers for each monitor
+- **Per-output configuration**: Set different wallpapers and settings for each
+  monitor
+  - **Global and per-output settings**: Override defaults for specific monitors
+  - **Performance tuning**: Adjustable downsampling limits and quality
+    thresholds
 - **Multiple image formats**: Supports JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC,
   PPM, PGM
 - **EGL/OpenGL rendering**: Hardware-accelerated wallpaper rendering
 - **Configuration file support**: Easy setup with INI-style config files
 - **Signal handling**: Graceful shutdown and configuration reload (SIGHUP)
+- **Intelligent downsampling**: Automatically reduces large image resolution to
+  save memory (up to 94% memory savings for 8K images)
+- **Advanced filtering**: Nearest, linear, bilinear, and trilinear filtering
+  options
