• macOS: Pods, build artifacts
• Windows: Visual Studio, build outputs
• Linux: Build artifacts, CMake files
• Web: Build outputs, dependencies

Security & Sensitive Data

• API keys and secrets
• Certificates and keys
• Database files
• Environment files
• Backup files

Development Tools

• IDE configurations (IntelliJ, VS Code, Sublime)
• Editor temporary files
• Node.js dependencies
• Log files and temporary data

🚀 Quick Start
