+## Requirements
+
+- **Interactive Terminal**: The library requires a TTY (interactive terminal) to function properly
+- **Bash 4.0+**: Uses associative arrays and other modern bash features
+- **Standard utilities**: `tput`, `grep`, `sed` (usually pre-installed)
+
+**Note**: The library will detect non-interactive terminals and exit gracefully with appropriate warnings.
+
 ## Quick Start
