+Use it as follows: build.sh -m "useful comment on changes being made"
+
+When making TUI menus, try to use the first leter of the command and the key to press to execute that command. For example, if the command is "Open file" try to use a keypress of "o" upper or lower case to signal to open the file. Use this instead of number keyed menus when possible. In the command, the letter should be underlined that signifies the command.

-r# OTP Cipher - One Time Pad Implementation
+# OTP Cipher - One Time Pad Implementation
 
 A secure one-time pad (OTP) cipher implementation in C with automatic versioning system.
 
 ## Features
 
 - **Perfect Security**: Implements true one-time pad encryption with information-theoretic security
+- **Text & File Encryption**: Supports both inline text and file encryption
+- **Multiple Output Formats**: Binary (.otp) and ASCII armored (.otp.asc) file formats
 - **Keyboard Entropy**: Optional keyboard entropy collection for enhanced randomness
+- **Short Command Flags**: Convenient single-character flags for all operations
 - **Automatic Versioning**: Built-in semantic versioning with automatic patch increment
 - **Multiple Build Options**: Standard and static linking builds
 - **Cross-Platform**: Works on Linux and other UNIX-like systems

-## Examples
+## File Formats
+
+### .otp File Format (Binary)
+
+Binary encrypted files use a structured header format:
+
+```
+Offset | Size | Field               | Description
+-------|------|-------------------|----------------------------------
+0      | 4    | Magic             | "OTP\0" - File type identifier
+4      | 2    | Version           | Format version (currently 1)
+6      | 32   | Pad Checksum      | Binary pad checksum (32 bytes)
+38     | 8    | Pad Offset        | Offset in pad file (uint64_t)
+46     | 4    | File Mode         | Original file permissions (uint32_t)
+50     | 8    | File Size         | Original file size (uint64_t)
+58     | var  | Encrypted Data    | XOR-encrypted file contents
+```
+
+### .otp.asc File Format (ASCII Armored)
+
+ASCII armored files use the same format as encrypted text messages:
+
+```
+-----BEGIN OTP MESSAGE-----
+Version: v0.2.15
+Pad-ChkSum: <64-character-hex-checksum>
+Pad-Offset: <decimal-offset-value>
+
+<base64-encoded-encrypted-data>
+-----END OTP MESSAGE-----
+```
+
+**Note:** ASCII armored files do not preserve original file permissions metadata.
+
+## Usage Examples
+
+### Short Command Flags
+```bash
+# Quick commands using short flags
+./otp -g 1GB                    # Generate 1GB pad
+./otp -l                        # List available pads
+./otp -e 1a2b "Hello world"     # Encrypt text inline
+./otp -d "-----BEGIN OTP..."    # Decrypt message inline
+
+# File operations
+./otp -f document.pdf 1a2b                # Encrypt file (binary)
+./otp -f document.pdf 1a2b -a             # Encrypt file (ASCII)
+./otp -f document.pdf 1a2b -o secret.otp  # Custom output name
+```
+
+### Text Encryption
+```bash
+# Interactive text encryption
+./otp encrypt 1a2b3c
+Enter text to encrypt: This is my secret message
+# Outputs ASCII armored message
+
+# Inline text encryption
+./otp -e 1a2b3c "This is my secret message"
+# Outputs ASCII armored message immediately
+```
+
+### File Encryption
+```bash
+# Binary format (preserves metadata)
+./otp -f sensitive.doc a1b2c3
+
+# ASCII armored format (text-safe)
+./otp -f sensitive.doc a1b2c3 -a
+
+# Custom output filename
+./otp -f sensitive.doc a1b2c3 -o encrypted_document.otp
+```
+
+### Decryption
+```bash
+# Auto-detect format and pad from message/file
+./otp -d encrypted.otp.asc
+./otp -d "-----BEGIN OTP MESSAGE-----..."
+
+# Interactive mode
+./otp decrypt
+# Prompts for encrypted message input
+```
