+## 🛠️ Development Configuration
+
+This repository uses various configuration files to ensure consistent code style and avoid issues with line endings:
+
+- [`.editorconfig`](.editorconfig) - Defines coding styles across different editors and IDEs
+- [`.gitattributes`](.gitattributes) - Ensures consistent line endings in text files
+- [`.vscode/settings.json`](.vscode/settings.json) - VS Code-specific settings for this repository
+- [`.vscode/extensions.json`](.vscode/extensions.json) - Recommended VS Code extensions
+
+> 💡 **Note**: All markdown files in this repository use LF line endings (Unix-style) to avoid mixed line endings issues. The repository is configured to automatically handle line endings conversion.
