-## Features
+## Why CDNS?
+
+- **🔐 Privacy in a click**: Easily switch to trusted providers like Quad9, Cloudflare, or AdGuard for a more secure browsing experience.
+- **✨ Terminal-first**: A clean, reactive TUI that makes managing network settings actually enjoyable.
+- **🧠 Zero-config discovery**: It just works. Whether you're on NetworkManager, systemd-resolved, or a plain old resolv.conf, CDNS finds it and handles the heavy lifting.
+- **🚑 Fail-safe**: Messed something up? Roll back to your previous configuration instantly with zero stress.
+
+## Compatibility

+While CDNS is designed to work across any Linux distribution using standard networking stack, here is the current status:
 
-- **🛡️ Privacy Focused**: Quickly switch to encrypted/private DNS providers like Quad9, Cloudflare, or AdGuard.
-- **🖥️ Interactive TUI**: Beautiful terminal interface powered by Bubble Tea.
-- **🔌 Multi-Backend**: Automatically detects and handles `NetworkManager`, `systemd-resolved`, and traditional `/etc/resolv.conf`.
-- **↩️ Safe Reverts**: Automatic state backup allowing quick rollback if things go wrong.
