-It should work across platforms if compiled for that platform.
+The Scream Cipher encodes text by replacing each character with an 'A' modified by diacritic marks. This ensures all messages appear as a string of 'A's while still carrying the original meaning.
+
+## Features
+
+✔ **Encode** text into the Scream Cipher.  
+✔ **Decode** Scream Cipher text back into ASCII.  
+✔ **Cross-platform compatibility** when compiled for the target system.  
+✔ **UTF-8 support** for proper diacritic display.
