+# Development Guide
+
+Comprehensive guide for developing and contributing to gh-action-readme.
+
+## 🚨 CRITICAL: README Protection
+
+**NEVER overwrite `/README.md`** - The root README.md is the main project documentation.
+
+**For testing generation commands:**
+
+```bash
+# New enhanced targeting (recommended)
+gh-action-readme gen testdata/example-action/
+gh-action-readme gen testdata/composite-action/action.yml
+
+# Traditional method (still supported)
+cd testdata/
+../gh-action-readme gen [options]
+```
+
+## 🛠️ Development Setup
+
+### Prerequisites
+
+- **Go 1.24+** (required)
+- **golangci-lint** (for linting)
+- **pre-commit** (for git hooks)
+- **Docker** (optional, for containerized testing)
+
+### Quick Start
+
+```bash
+# Clone repository
+git clone https://github.com/ivuorinen/gh-action-readme.git
+cd gh-action-readme
+
+# Install development tools
+make devtools
+
+# Install pre-commit hooks
+make pre-commit-install
+
+# Build and test
+make build
+make test
+make lint
+```
+
+## 🏗️ Architecture
+
+### Core Components
+
+- **`main.go`** - CLI with Cobra framework, enhanced gen command
+- **`internal/generator.go`** - Core generation logic with custom output paths
+- **`internal/config.go`** - Viper configuration (XDG compliant)
+- **`internal/output.go`** - Colored terminal output with progress bars
+- **`internal/errors/`** - Contextual error handling with suggestions
+- **`internal/wizard/`** - Interactive configuration wizard
+- **`internal/progress.go`** - Progress indicators for batch operations
+
+### Template System
+
+- **`templates/readme.tmpl`** - Default template
+- **`templates/themes/`** - Theme-specific templates
+  - `github/` - GitHub-style with badges
+  - `gitlab/` - GitLab CI/CD focused
+  - `minimal/` - Clean, concise
+  - `professional/` - Comprehensive with ToC
+  - `asciidoc/` - AsciiDoc format
+
+### Testing Framework
+
+- **`testutil/`** - Comprehensive testing utilities
+- **`testdata/`** - Test fixtures and sample actions
+- **Table-driven tests** - Consistent testing patterns
+- **Mock implementations** - Isolated unit tests
+
+## 🧪 Testing Strategy
+
+### Running Tests
+
+```bash
+# All tests
+make test
+
+# With coverage
+make test-coverage
+
+# Specific package
+go test ./internal/generator
+
+# Verbose output
+go test -v ./...
+
+# Race condition detection
+go test -race ./...
+```
+
+### Test Types
+
+**Unit Tests** (`*_test.go`):
+
+```bash
+go test ./internal        # Core logic tests
+go test ./testutil        # Test framework tests
+```
+
+**Integration Tests** (`*_integration_test.go`):
+
+```bash
+go test -tags=integration ./...
+```
+
+**Comprehensive Tests** (`comprehensive_test.go`):
+
+```bash
+go test ./internal -run Comprehensive
+```
+
+### Testing Best Practices
+
+1. **Use testutil framework** for consistent test patterns
+2. **Table-driven tests** for multiple scenarios
+3. **Mock external dependencies** (GitHub API, filesystem)
+4. **Test error conditions** and edge cases
+5. **Verify thread safety** with race detection
+
+### Test Coverage
+
+Current coverage: **51.2%** overall
+
+- **Cache module**: 91.4%
+- **Errors module**: 91.5%
+- **Git detector**: 78.4%
+- **Validation**: 76.2%
+
+Target: **>80%** coverage for all new code
+
+## 🔧 Build System
+
+### Makefile Targets

+make clean              # Clean build artifacts
+
+# Testing
+make test               # Run all tests
+make test-coverage      # Run tests with coverage

+
+# Dependencies
+make deps-check         # Check outdated dependencies
+make deps-update        # Interactive dependency updates
+```
+
+### Build Configuration
+
+```bash
+# Build with version info
+go build -ldflags "-X main.version=v1.0.0 -X main.commit=$(git rev-parse HEAD)"
+
+# Cross-platform builds (handled by GoReleaser)
+GOOS=linux GOARCH=amd64 go build
+GOOS=darwin GOARCH=arm64 go build
+GOOS=windows GOARCH=amd64 go build
+```
+
+## 📝 Code Style & Quality
+
+### Linting Configuration
+
+- **golangci-lint** with 35+ enabled linters
+- **EditorConfig** compliance required
+- **Pre-commit hooks** for automated checking
+- **Zero linting violations** policy
+
+### Code Quality Standards
+
+- ✅ **Cyclomatic complexity** <10 for all functions
+- ✅ **Test coverage** >80% for critical modules
+- ✅ **Error handling** for all possible errors
+- ✅ **Documentation** for all exported functions
+- ✅ **Thread safety** for concurrent operations
+
+### Formatting Rules
+
+```bash
+# Auto-format code
+make format
+
+# Check formatting
+gofmt -d .
+goimports -d .
+```
+
+## 🔄 Adding New Features
+
+### New Theme
+
+1. Create `templates/themes/THEME_NAME/readme.tmpl`
+2. Add to `resolveThemeTemplate()` in `config.go`
+3. Update `configThemesHandler()` in `main.go`
+4. Add tests and documentation
+
+### New Output Format
+
+1. Add constant to `generator.go`
+2. Add case to `GenerateFromFile()` switch
+3. Implement `generate[FORMAT]()` method
+4. Update CLI help and documentation
+
+### New CLI Command
+
+1. Add command in `main.go` using Cobra
+2. Implement handler function
+3. Add flags and validation
+4. Write tests and update documentation
+
+### New Template Functions
+
+Add to `templateFuncs()` in `internal/template.go`:
+
+```go
+"myFunction": func(input string) string {
+    // Implementation
+    return processed
+},
+```
+
+## 🚀 Performance Optimization
+
+### Profiling
+
+```bash
+# CPU profiling
+go test -cpuprofile=cpu.prof -bench=.
+go tool pprof cpu.prof
+
+# Memory profiling
+go test -memprofile=mem.prof -bench=.
+go tool pprof mem.prof
+
+# Benchmark testing
+go test -bench=. -benchmem
+```
+
+### Performance Guidelines
+
+- **Use sync.Pool** for frequently allocated objects
+- **Implement caching** for expensive operations
+- **Minimize memory allocations** in hot paths
+- **Concurrent processing** for I/O bound operations
+- **Profile before optimizing**
+
+## 🔐 Security Practices
+
+### Security Scanning
+
+```bash
+make security           # Run all scans
+make vulncheck         # Go vulnerabilities
+make trivy             # Filesystem scan
+make gitleaks          # Secrets detection
+```
+
+### Secure Coding
+
+- **Validate all inputs** especially user-provided data
+- **Use secure defaults** for all configurations
+- **Sanitize file paths** to prevent directory traversal
+- **Handle secrets safely** never log or expose tokens
+- **Regular dependency updates** with security patches
+
+### GitHub Token Handling
+
+```go
+// ❌ Wrong - logging token
+log.Printf("Using token: %s", token)
+
+// ✅ Correct - masking sensitive data
+log.Printf("Using token: %s", maskToken(token))
+
+func maskToken(token string) string {
+    if len(token) < 8 {
+        return "***"
+    }
+    return token[:4] + "***" + token[len(token)-4:]
+}
+```
+
+## 📚 Documentation
+
+### Documentation Standards
+
+- **godoc comments** for all exported functions
+- **README updates** for user-facing changes
+- **CHANGELOG entries** following Keep a Changelog format
+- **Architecture Decision Records** for significant changes
+
+### Writing Guidelines
+
+```go
+// Package generator provides core documentation generation functionality.
+//
+// The generator processes GitHub Action YAML files and produces formatted
+// documentation in multiple output formats (Markdown, HTML, JSON, AsciiDoc).
+package generator
+
+// GenerateReadme creates formatted documentation from an ActionYML struct.
+//
+// The function applies the specified theme and output format to generate
+// comprehensive documentation including input/output tables, usage examples,
+// and metadata sections.
+//
+// Parameters:
+//   - action: Parsed action.yml data structure
+//   - theme: Template theme name (github, gitlab, minimal, professional, default)
+//   - format: Output format (md, html, json, asciidoc)
+//
+// Returns formatted documentation string and any processing error.
+func GenerateReadme(action *ActionYML, theme, format string) (string, error) {
+    // Implementation...
+}
+```
