 USBGuard is a software framework for implementing a USB device authorization policy (allowlisting/blocklisting). It protects your system against rogue USB devices by scanning them and checking their parameters against a set of rules.
 
-Built with [bubbletea](https://github.com/charmbracelet/bubbletea) & Goland!
+<img alt="USBGuard-tui demo" src="./.github/assets/demo.gif" width="600" />
+
+Built with [bubbletea](https://github.com/charmbracelet/bubbletea) & Golang!
+
+Colors and styles can be customized using [ilovetui](https://github.com/anotherhadi/ilovetui), which applies theme changes across all compatible TUI applications at once.
+
+## Features
+
+- List all connected USB devices with their current status (allowed, blocked, rejected)
+- Allow, block, or reject devices: temporarily or permanently
+- Action popup with mouse support for quick device management
+- Filter devices by name with `/`
+- Auto-refresh
+- Keyboard shortcuts for all actions (`a`/`A`, `b`/`B`, `e`/`E`)
 
 ## Requirements
