+
+### Architecture Overview
+
+Freedom Loader uses a client-server architecture within a single Electron application:
+
+- **Frontend**: HTML/CSS/JavaScript served via Electron's renderer process
+- **Backend**: Express.js server running locally for download management
+- **App modules**: Electron-specific logic (window, IPC, updates, RPC) isolated in `app/`
+- **IPC Bridge**: Secure communication via Electron's preload script
+- **Logging**: Winston-based structured logging with file rotation
+- **Updates**: Automatic checking and installation via electron-updater
+
+## Theme Workshop
+
+Freedom Loader includes a web-based theme creator available at [Freedom Loader Workshop](https://masteracnolo.github.io/Freedom-Loader-Workshop/).
+
+- Create custom themes with a live preview of the actual UI
+- Browse and download community themes
+- Export themes as `.zip` files ready to drop into the `theme/` folder
+- Supports background images, custom colors for every UI element
+
+### Installing a custom theme
+1. Download a `.zip` theme file
+2. Drop it in the `theme/` folder of your Freedom Loader installation
+3. Restart the app — your theme appears in the settings panel

+
+- **No Data Collection**: We don't collect, store, or transmit your personal data
+- **No Telemetry**: No usage tracking or analytics
+- **Local Operation**: All downloads are processed locally on your machine
+- **Optional Features**: Discord RPC is optional and can be disabled
+
+## Known Security Considerations
+
+### Browser Cookie Access
+
+Freedom Loader accesses Firefox cookies to download protected content. This is:
+
+- **By Design**: Required for age-restricted or member-only content
+- **Local Only**: Cookies are read locally and never transmitted
+- **User Controlled**: You can control what content you download
+
+### Native Dependencies
+
+Freedom Loader bundles native binaries:
+
+- **yt-dlp**: Official builds from [yt-dlp/yt-dlp](https://github.com/yt-dlp/yt-dlp)
+- **FFmpeg**: Official builds from [FFmpeg.org](https://ffmpeg.org/)
+- **Deno**: Official builds from [Deno.land](https://deno.land/)
+
+These dependencies are verified and updated regularly.
+
+### Windows Defender Warnings
+
+New releases may trigger Windows Defender warnings because:
+
+- The application is not yet widely distributed
+- Code signing certificates are expensive for open-source projects
+
+This is expected behavior for new releases. The warning will decrease as more users download the software.
+
+## Vulnerability Disclosure Policy
+
+### Our Commitment
+
+We are committed to:
+
+- Responding promptly to security reports
+- Working with security researchers to verify and address issues
+- Keeping users informed about security updates
+- Crediting researchers who report vulnerabilities responsibly
+
+### Disclosure Timeline
+
+1. **Day 0**: Vulnerability reported privately
+2. **Day 1-2**: Acknowledgment sent to reporter
+3. **Day 3-7**: Vulnerability assessed and fix developed
+4. **Day 7-14**: Fix released (critical vulnerabilities prioritized)
+5. **Day 14+**: Public disclosure (coordinated with reporter)
+
+### Scope
+
+Security issues we're most interested in:
+
+- **Code Execution**: Arbitrary code execution vulnerabilities
+- **Path Traversal**: Issues with file system access controls
+- **Injection**: Command injection or similar vulnerabilities
+- **Authentication**: Bypass of security controls
+- **Data Exposure**: Unintended exposure of sensitive data
+
+### Out of Scope
+
+The following are generally not considered security vulnerabilities:
+
+- Issues requiring physical access to the user's machine
+- Social engineering attacks
+- Denial of service against third-party services
+- Issues in third-party dependencies (report to upstream projects)
+- Missing security headers on local HTTP server (no remote access)
+
+## Security Updates
+
+Security updates are released as:
+
+- **Patch Releases**: For critical security fixes (e.g., 1.4.1 → 1.4.2)
+- **Automatic Updates**: Users are notified via the built-in update system
+- **Release Notes**: Security fixes are clearly marked in changelog
+
+## Additional Resources
+
+- [Contributing Guidelines](CONTRIBUTING.md)
+- [Code of Conduct](CODE_OF_CONDUCT.md)
+- [GitHub Security Advisories](https://github.com/MasterAcnolo/Freedom-Loader/security/advisories)
