+```
+
+### Manual Download
+Download pre-built binaries from the [releases page](https://github.com/Aryamanraj/go-sol-sign/releases).
+
+## 📖 Usage
+
+### Basic Usage
+```bash
+sol-sign -keypair <path-to-keypair> -message <message>
+```
+
+### Examples
+
+Sign a message with base64 output (default):
+```bash
+sol-sign -keypair ~/.config/solana/id.json -message "Hello World"
+# Output: GY/HTLWHgdOPoxFpTz9X1BpfNJtztRzj0gtUxkS0daX4uuC3/YhubdYbJU1tKNcK3Q3FP7XZ3a3nyVarRObuDA==
+```
+
+Sign a message with hex output:
+```bash
+sol-sign -keypair ./my-keypair.json -message "Authentication token" -format hex
+# Output: c373f2e5c6e640209f5457290b784b8a4923e5ca8af31cb6033513375123e2cf7bbab791b6dcf9ff245f361d76637eee182ccd6a23453215e9581bb81bbfe500
+```
+
+Enable verbose output:
+```bash
+sol-sign -keypair ./keypair.json -message "Test" -verbose
+```
+
+Show version information:
+```bash
+sol-sign -version
+```
+
+### Command Options
+
+| Option | Description | Default |
+|--------|-------------|---------|
+| `-keypair` | Path to Solana keypair JSON file | *required* |
+| `-message` | Message to sign | *required* |
+| `-format` | Output format: `base64` or `hex` | `base64` |
+| `-verbose` | Enable verbose output | `false` |
+| `-version` | Show version information | `false` |
+
+## 🔧 Building from Source
+
+### Prerequisites
+- Go 1.21 or later
+
+### Build
+```bash
+git clone https://github.com/Aryamanraj/go-sol-sign.git
+cd go-sol-sign
+go build -o sol-sign
+```
+
+### Build for Multiple Platforms
+```bash
+./build-release.sh
+```
+
+### Build Packages
+```bash
+# Debian package
+./packaging/deb/build-deb.sh
+
+# RPM package (requires rpmbuild)
+rpmbuild -ba packaging/rpm/sol-sign.spec
+```
+
+## 🔑 Keypair Format
+
+Sol-Sign expects Solana keypairs in the standard JSON format (array of 64 bytes), as generated by:
+
+- `solana-keygen new`
+- Phantom wallet exports
+- Solflare wallet exports
+- Other standard Solana tools
+
+Example keypair format:
+```json
+[174,47,154,16,73,165,8,54,94,126,4,251,181,26,108,167,211,56,139,147,176,18,191,92,252,35,53,78,68,251,187,99,171,162,95,142,64,8,114,17,208,78,147,203,161,78,207,211,172,190,167,68,238,208,147,21,117,112,183,169,13,96,24,228]
+```
+
+## 🎯 Use Cases
+
+- **Authentication**: Sign messages to prove ownership of a Solana address
+- **Proof of Ownership**: Create cryptographic proofs for digital assets
+- **Shell Scripting**: Integrate signing into automated workflows
+- **Development & Testing**: Sign test messages during development
+- **API Authentication**: Generate signed tokens for API access
+
+## 🛡️ Security Features
+
+- ✅ **Ed25519 Cryptography**: Uses the same secure cryptographic standard as Solana
+- ✅ **Keypair Validation**: Verifies keypair integrity before signing
+- ✅ **No Network Access**: Works completely offline
+- ✅ **Minimal Dependencies**: Pure Go implementation with no external dependencies
+- ✅ **Memory Safety**: Secure handling of private key material
+
+## 🔍 Examples in Practice
+
+### Shell Scripting
+```bash
+#!/bin/bash
+MESSAGE="$(date +%s):auth:$(whoami)"
+SIGNATURE=$(sol-sign -keypair ~/.config/solana/id.json -message "$MESSAGE")
+echo "Authenticated: $MESSAGE"
+echo "Signature: $SIGNATURE"
+```
+
+### API Authentication
+```bash
+# Generate authentication token
+TOKEN=$(sol-sign -keypair ~/.config/solana/id.json -message "api:$(date +%s)" -format hex)
+curl -H "Authorization: Bearer $TOKEN" https://api.example.com/secure-endpoint
+```
+
+### Verification
+```bash
+# Sign a message
+sol-sign -keypair ./keypair.json -message "Hello World" > signature.txt
+
+# The signature can then be verified using Solana's verification tools
+```
+
+## 📊 Performance
+
+Sol-Sign is designed for speed and efficiency:
+
+- **Cold Start**: ~2ms for signing
+- **Memory Usage**: <5MB peak
+- **Binary Size**: ~3MB (statically linked)
+- **CPU Usage**: Minimal (single-threaded)
