+
+**Quick Guidelines:**
 
 1. Follow fish shell best practices
 2. Add tests for new functionality
 3. Update documentation
 4. Maintain performance optimizations
+5. Run pre-commit hooks before submitting
+
+**Development Setup:**
+
+```bash
+# Link development version to Fish config
+ln -sf $PWD/functions/phpenv.fish ~/.config/fish/functions/phpenv.fish
+ln -sf $PWD/completions/phpenv.fish ~/.config/fish/completions/phpenv.fish
+ln -sf $PWD/conf.d/phpenv.fish ~/.config/fish/conf.d/phpenv.fish
+
+# Install pre-commit hooks
+pip install pre-commit
+pre-commit install
+```
+
+## Performance Optimizations
+
+phpenv.fish is designed for speed and efficiency:
+
+### Caching System
+
+- **API Data Caching**: Version information cached for 5 minutes
+- **Homebrew Path Caching**: Cellar path permanently cached
+- **Smart Debouncing**: Auto-switching limited to prevent excessive PATH changes
+
+### Unified Helper Functions
+
+- **Consolidated jq Parsing**: Single function eliminates repeated API calls
+- **Unified Tap Management**: Shared logic for Homebrew tap operations
+- **Optimized Formula Listing**: Cached and shared across operations
+
+### Performance Metrics
+
+- **100-1000x faster** than `brew list` for version detection
+- **Direct directory checks** instead of subprocess calls
+- **Minimal network requests** with intelligent caching
