 # About
-Java program using `dd` to make flashing iso and image files easier on the terminal. This program allows anyone to flash iso and image files without having to search for extra GUI tools by keeping it simple and resource-friendly.
+Small and lightweight wrapper written in Java for `dd` designed to simplify CLI flashing while protecting your hardware from accidental command-line errors. cflash replaces the syntax with a clear, safe interface, providing a reliable workflow for both newcomers and power users.
