cargo build --release

# Run tests
cargo test --all-features

# Install system-wide
cargo install --path .
```

### Development Environment
```bash
# Install development dependencies
make setup

# Run with hot reload
make dev-watch

# Quick development cycle
make dev
```

## Installation

### From Source
```bash
# Clone and build
git clone <repository-url>
cd password_manager
cargo install --path .

# Verify installation
password_manager --help
```

### From crates.io (after publishing)
```bash
# Install from crates.io
cargo install password_manager

# Verify installation
password_manager --help
```

### From GitHub Releases
```bash
# Download appropriate binary for your platform
# Linux: password_manager-linux-x86_64.tar.gz
# macOS: password_manager-macos-x86_64.tar.gz
# Windows: password_manager-windows-x86_64.zip

# Extract and add to PATH
tar -xzf password_manager-linux-x86_64.tar.gz
sudo mv password_manager /usr/local/bin/
```

## CI/CD Pipeline

### GitHub Actions Workflows

The project includes several automated workflows:

1. **CI Pipeline** (`.github/workflows/ci.yml`)
   - Runs on every push and PR
   - Tests with multiple Rust versions
   - Security audits and code coverage
   - Format and linting checks

2. **Build and Release** (`.github/workflows/build.yml`)
   - Triggered by version tags
   - Cross-platform builds
   - Creates GitHub releases
   - Publishes to crates.io

3. **Security Scanning** (`.github/workflows/security.yml`)
   - Daily security audits
   - Dependency vulnerability checks
   - Code scanning with multiple tools

4. **Dependency Updates** (`.github/workflows/dependencies.yml`)
   - Weekly dependency updates
   - Automated PR creation
   - Security validation

### Setting Up CI/CD

1. **Fork the Repository**
   ```bash
   git clone <your-fork>
   cd password_manager
   ```

2. **Configure Secrets**
   - Go to Settings → Secrets and variables → Actions
   - Add `CARGO_REGISTRY_TOKEN` for crates.io publishing
   - Add `SNYK_TOKEN` for security scanning (optional)

3. **Enable Actions**
   - Go to Settings → Actions → General
   - Enable "Allow all actions and reusable workflows"

### Manual Release Process
```bash
# Create a new release
./scripts/release.sh 1.0.0

# This will:
# 1. Update version in Cargo.toml
# 2. Run tests and security audit
# 3. Create git tag
# 4. Push changes
# 5. Trigger GitHub Actions release workflow
```

## Release Process

### Automated Release
1. Create a version tag: `git tag v1.0.0`
2. Push the tag: `git push origin v1.0.0`
3. GitHub Actions automatically:
   - Builds for all platforms
   - Creates GitHub release
   - Publishes to crates.io

### Manual Release Steps
```bash
# 1. Update version
cargo set-version 1.0.0

# 2. Run tests
cargo test --all-features

# 3. Security audit
cargo audit

# 4. Build release
cargo build --release

# 5. Create tag
git tag -a v1.0.0 -m "Release v1.0.0"

# 6. Push
git push origin main --tags

# 7. Create GitHub release manually
```

### Release Checklist

## Distribution

### Cross-Platform Builds
The CI/CD pipeline automatically builds for:
- **Linux**: x86_64, ARM64
- **macOS**: x86_64, ARM64 (Apple Silicon)
- **Windows**: x86_64

### Release Artifacts
Each release includes:
- Source code archive
- Platform-specific binaries
- Checksums for verification
- Release notes

### Installation Methods
1. **crates.io**: `cargo install password_manager`
2. **GitHub Releases**: Download binary for your platform
3. **Source**: `cargo install --git <repository>`

## Development Workflow

### Daily Development
```bash
# Setup development environment
make setup

# Quick development cycle
make dev

# Run tests
make test

# Security audit
make security

# Format code
make format
```

### Release Preparation
```bash
# Full test suite
make check-all

# Build release
make release

# Create release
make release-create
```

## Security Considerations

### Code Security
- Automated security audits
- Dependency vulnerability checks
- Code scanning with multiple tools
- Regular security updates

### Distribution Security
- Signed releases (when configured)
- Checksum verification
- Secure download channels
- Vulnerability disclosure process

### Best Practices
1. **Regular Updates**: Keep dependencies updated
2. **Security Audits**: Run `cargo audit` regularly
3. **Code Review**: Review all changes before merging
4. **Testing**: Comprehensive test coverage
5. **Documentation**: Keep docs updated

## Troubleshooting

### Common Issues

1. **Build Failures**
   ```bash
   # Clean and rebuild
   make clean
   make build
   ```

2. **Test Failures**
   ```bash
   # Run tests with verbose output
   cargo test --verbose
   ```

3. **Security Audit Failures**
   ```bash
   # Update dependencies
   cargo update
   
   # Check for vulnerabilities
   cargo audit
   ```

4. **Installation Issues**
   ```bash
   # Check Rust version
   rustc --version
   
   # Update Rust
   rustup update
   ```

### Debug Mode
```bash
# Run with debug logging
RUST_LOG=debug cargo run

# Build with debug symbols
cargo build --debug
```

## Support

For deployment issues:
1. Check the logs for error messages
2. Verify all prerequisites are met
3. Review security configuration
4. Check Rust toolchain version

For CI/CD issues:
1. Check GitHub Actions logs
2. Verify secrets are configured
3. Review workflow permissions
4. Check branch protection rules
