+# Development Guide - Front Matter Lite
+
+## Prerequisites
+
+- Node.js (v18 or higher)
+- npm or yarn
+
+## Setup
+
+```bash
+cd lite
+npm install
+```
+
+## Building
+
+### Development Build
+
+```bash
+npm run dev
+```
+
+This will watch for changes and rebuild automatically.
+
+### Production Build
+
+```bash
+npm run build
+```
+
+## Testing
+
+### Local Testing
+
+1. Build the extension:
+   ```bash
+   npm run build
+   ```
+
+2. Press F5 in VS Code to open the Extension Development Host
+
+3. Test in a virtual workspace:

+   - Install the extension manually
+
+## Architecture
+
+The lite version is designed to work without Node.js-specific APIs:
+
+- **No Node.js fs module** - Uses `vscode.workspace.fs` instead
+- **No Node.js path module** - Uses `vscode.Uri.joinPath` instead
+- **No child_process** - No external script execution
+- **Browser-compatible** - Built as a web extension (target: 'webworker')
+
+## Key Differences from Full Extension
+
+| Feature | Full Extension | Lite Version |
+|---------|---------------|--------------|
+| File Operations | Node.js `fs` | VS Code `workspace.fs` |
+| Path Handling | Node.js `path` | `vscode.Uri` |
+| Scripts | child_process | Not available |
+| Workspace | File system only | Virtual workspaces |
+| Dashboard | Full React app | Simplified (planned) |
+
+## Contributing
+
+When adding features to the lite version:
+
+1. Ensure compatibility with virtual workspaces
+2. Use only browser-compatible APIs
+3. Test in both github.dev and vscode.dev
+4. Document any limitations
+
+## Debugging

+Virtual workspaces allow you to work with code directly in your browser without cloning a repository locally. This includes:
+
+- **github.dev** - Press `.` on any GitHub repository
+- **vscode.dev** - Open VS Code in your browser
+- **GitHub Codespaces** - Cloud-based development environments
+
+## Features
+
+The lite version provides core content management functionality:
+
+### ✅ Supported Features
+
+- **Metadata Panel** - View and edit front matter for the currently open markdown file
+- **Register Content Folders** - Right-click on folders in the Explorer to register them as content folders
+- **Create Content** - Create new markdown files with front matter
+- **View Configuration** - Manage your content folder settings
+
+### ❌ Limited/Unavailable Features
+
+The following features from the full extension are not available in the lite version due to virtual workspace limitations:
+
+- **Dashboard** - Full dashboard UI (basic version available)
+- **Media Management** - File upload and media library
+- **Local Server Preview** - Starting/stopping local dev servers
+- **Git Integration** - Advanced git operations
+- **Custom Scripts** - Running custom Node.js scripts

+```
+
+## Troubleshooting
+
+### Extension Not Showing Up
+
+1. **Check Extension is Installed:**
+   - Open Extensions view (Ctrl/Cmd+Shift+X)
+   - Search for "Front Matter Lite"
+   - Verify it's installed and enabled
+
+2. **Check Output Channel:**
+   - View > Output
+   - Select "Front Matter Lite" from dropdown
+   - Look for activation message
+
+### No Folders Showing in Dashboard
+
+1. **Verify folders are registered:**
+   - Check settings: `frontMatter.content.pageFolders`
+   - Ensure paths are relative to workspace root
+   - Click "Refresh" button in dashboard
+
+2. **Check workspace:**
+   - Ensure you have a workspace/folder open
+   - Verify the workspace contains the specified paths
+
+### Can't Create Content
+
+1. **Verify folder is registered:**
+   - At least one folder must be in `frontMatter.content.pageFolders`
+
+2. **Check permissions:**
+   - Ensure you have write access to the repository
+   - In github.dev, you need to fork or have write access
+
+### Files Not Appearing
+
+1. **Click "Refresh":**
+   - Dashboard doesn't auto-update
+   - Click the "Refresh" button
+
+2. **Check file extensions:**
+   - Only .md, .mdx, and .markdown files are shown
+   - Check your files have the correct extension
+
+## Best Practices
+
+### 1. Organize Content by Type
+
+```json
+{
+  "frontMatter.content.pageFolders": [
+    { "title": "Blog Posts", "path": "content/blog" },
+    { "title": "Tutorials", "path": "content/tutorials" },
+    { "title": "Documentation", "path": "docs" }
+  ]
+}
+```
+
+### 2. Use Consistent Front Matter
+
+Define a template for all your content:
+
+```markdown
+---
+title: Post Title
+description: Brief description
+date: 2024-01-07T10:00:00.000Z
+tags: []
+categories: []
+draft: false
+---
+```
+
+### 3. Commit Configuration
+
+Add `.vscode/settings.json` to your repository so all team members have the same setup.
+
+### 4. Regular Backups
+
+Even though you're in a virtual workspace:
+- Commit changes regularly
+- Push to GitHub frequently
+- Use branches for experiments

+# Front Matter Lite - Implementation Summary
+
+## Overview
+
+Front Matter Lite is a web extension that brings core Front Matter CMS functionality to virtual workspaces like github.dev, vscode.dev, and GitHub Codespaces. It addresses the original issue where users could not manage content in virtual workspaces.
+
+## Problem Statement (Original Issue)
+
+Users reported being unable to:
+1. Select/register virtual workspace folders as content folders
+2. Create content in virtual workspaces
+3. Use the dashboard in github.dev or vscode.dev
+4. Access basic Front Matter CMS functionality without cloning repositories locally
+
+## Solution
+
+Created a standalone lite web extension that:
+- Works exclusively with VS Code FileSystem API (no Node.js dependencies)
+- Provides folder registration via context menu
+- Enables content creation with front matter templates
+- Displays dashboard with content listing
+- Detects and adapts to virtual workspace environments
+
+## Architecture
+
+### Technology Stack
+- **TypeScript**: Type-safe development
+- **Webpack**: Bundling with 'webworker' target
+- **VS Code API**: FileSystem, Uri, workspace APIs only
+- **Webview API**: For dashboard UI
+
+### Key Design Decisions
+
+1. **Separate Extension**: Created as standalone to avoid breaking changes to main extension
+2. **No Node.js**: All file operations use `vscode.workspace.fs`
+3. **No External Dependencies**: Minimal bundle size, faster loading
+4. **Browser-Compatible**: Works in any VS Code environment
+5. **Configuration Reuse**: Uses same settings structure as main extension

+
+## Conclusion
+
+Front Matter Lite successfully addresses the original issue by providing a functional, secure, and well-documented web extension for virtual workspaces. It maintains the core value proposition of Front Matter CMS while working within browser constraints.
+
+The implementation is production-ready pending manual testing in real-world virtual workspace scenarios.
+
+## Next Steps
+
+1. Manual testing in github.dev
+2. User feedback collection
+3. Iterate on UX based on feedback
+4. Consider marketplace publishing strategy

+# Testing Front Matter Lite
+
+This guide explains how to test the Front Matter Lite extension in various environments.
+
+## Prerequisites
+
+- Built extension (run `npm run build`)
+- VS Code installed locally OR
+- Access to github.dev/vscode.dev
+
+## Testing Methods
+
+### 1. Testing in VS Code Extension Development Host
+
+This is the fastest way to test during development:
+
+1. Open the lite folder in VS Code
+2. Build the extension: `npm run build`
+3. Press F5 to launch Extension Development Host
+4. In the new window, open a folder or workspace
+5. The Front Matter Lite sidebar should appear in the Activity Bar
+
+**To test virtual workspace features:**
+
+1. In Extension Development Host, open Command Palette (F1)
+2. Run "Open Remote Repository"
+3. Enter a GitHub repository URL (e.g., `https://github.com/username/repo`)
+4. The extension will activate in virtual workspace mode
+
+### 2. Testing in github.dev
+
+1. Package the extension:
+   ```bash
+   npm install -g @vscode/vsce
+   vsce package
+   ```
+
+2. This creates a `.vsix` file
+
+3. Navigate to github.dev:
+   - Go to any GitHub repository
+   - Press `.` (period key)
+   - OR change `github.com` to `github.dev` in the URL
+
+4. Install the extension:
+   - Click Extensions icon in Activity Bar
+   - Click "..." menu
+   - Choose "Install from VSIX..."
+   - Select the generated `.vsix` file
+
+5. Test the features
+
+### 3. Testing in vscode.dev
+
+Similar to github.dev:
+
+1. Go to https://vscode.dev
+2. Open a folder or repository
+3. Install the extension from VSIX (as above)
+
+## Test Scenarios
+
+### Scenario 1: Register a Content Folder
+
+1. Open a repository with markdown files
+2. In Explorer, right-click on a folder
+3. Select "Front Matter Lite > Register Content Folder (Lite)"
+4. Enter a title
+5. Verify:
+   - Success message appears
+   - Folder appears in Dashboard
+   - Configuration is saved
+
+### Scenario 2: Create Content
+
+1. Ensure at least one folder is registered
+2. Click "Create Content" in the Dashboard OR
+3. Run Command: "Front Matter Lite: Create Content (Lite)"
+4. Select a content folder
+5. Enter a file name
+6. Verify:
+   - File is created with front matter
+   - File opens in editor
+   - Front matter includes title, date, tags
+
+### Scenario 3: View Content in Dashboard
+
+1. Register a folder with existing markdown files
+2. Click "Refresh" in the Dashboard
+3. Verify:
+   - Files are listed
+   - File names and folders are shown
+   - Clicking a file opens it
+
+### Scenario 4: Virtual Workspace Detection
+
+1. Open repository via "Open Remote Repository" or github.dev
+2. Check Output channel "Front Matter Lite"
+3. Verify message: "Running in virtual workspace mode"
+4. Verify information message appears about limited features
+
+## Expected Behavior
+
+### Working Features ✅
+
+- ✅ Register content folders
+- ✅ Create new content files
+- ✅ View registered folders in dashboard
+- ✅ List content files in dashboard
+- ✅ Open files from dashboard
+- ✅ Basic front matter template
+- ✅ Virtual workspace detection
+
+### Known Limitations ❌
+
+- ❌ Cannot edit front matter in UI (use editor)
+- ❌ No media upload/management
+- ❌ No git integration
+- ❌ No custom scripts
+- ❌ No file system watch (manual refresh needed)
+- ❌ Limited to 100 files per folder
+
+## Debugging
+
+### Enable Logging
+
+1. View > Output
+2. Select "Front Matter Lite" from dropdown
+3. Check for error messages
+
+### Common Issues
+
+**Extension not appearing:**
+- Check that it's built: `npm run build`
+- Verify `dist/extension-web.js` exists
+- Check package.json has correct `browser` entry point
+
+**Commands not working:**
+- Check Output channel for errors
+- Verify workspace has folders
+- Ensure running in compatible environment
+
+**Dashboard not loading:**
+- Check browser console (if in github.dev/vscode.dev)
+- Verify webview is enabled
+- Check for Content Security Policy errors
+
+### Browser Console (github.dev/vscode.dev)
+
+1. Press F12 to open Developer Tools
+2. Check Console tab for JavaScript errors
+3. Check Network tab for failed requests
+
