+# Folder Structure
+
+This document outlines the folder structure of the plugin and explains the purpose of each directory.
+
+## Root Directories
+
+- **admin/** - Contains admin-specific functionality and assets
+- **includes/** - Contains core plugin functionality and classes
+- **languages/** - Contains translation files
+- **scripts/** - Contains build and deployment scripts
+- **.ai-workflows/** - Contains documentation for AI assistants
+- **.github/** - Contains GitHub-specific files like workflows
+- **.wordpress-org/** - Contains WordPress.org assets like banners and screenshots
+
+## Admin Directory Structure
+
+- **admin/css/** - Admin-specific CSS files
+- **admin/js/** - Admin-specific JavaScript files
+- **admin/images/** - Admin-specific images
+- **admin/partials/** - Admin-specific template partials
+- **admin/settings/** - Admin settings functionality
+- **admin/tools/** - Admin tools functionality
+- **admin/lib/** - Admin-specific library files and helper functions
+
+## Includes Directory
+
+The `includes/` directory contains the core plugin functionality:
+
+- **includes/admin.php** - Admin class for handling admin-specific functionality
+- **includes/core.php** - Core class for handling the main plugin functionality
+- **includes/modal.php** - Modal class for handling the update source selector modal
+- **includes/plugin.php** - Main plugin class that initializes all components
+- **includes/updater.php** - Updater class for handling plugin updates
+
+## File Naming Conventions
+
+- All PHP files in the `includes/` directory use lowercase filenames
+- All directories use lowercase names
+- JavaScript and CSS files use kebab-case (e.g., `update-source-selector.js`)
+
+## Best Practices
+
+1. **Unique Directory Names**: Each directory should have a unique name to avoid confusion
+2. **Logical Organization**: Files should be organized logically by function
+3. **Consistent Naming**: File and directory names should follow consistent naming conventions
+4. **Clear Separation**: Admin functionality should be separate from core functionality
+5. **Minimal Dependencies**: Files should have minimal dependencies on other files
+
+## @mentions for AI Assistants
+
+When referring to files or directories in AI conversations, use the following format:

+- **@includes/admin.php** - Admin functionality
+- **@includes/modal.php** - Modal functionality
+- **@includes/updater.php** - Updater functionality
+- **@admin/js/update-source-selector.js** - Update source selector JavaScript
