+# External binaries
+
+This project depends on three external tools that are **not bundled in the repository**.  
+You must download them manually and place each binary in the correct folder before building or running the app locally.
+
+---
+
+## Required tools
+
+| Tool    | Role                                        |
+|---------|---------------------------------------------|
+| yt-dlp  | Video and audio download engine             |
+| ffmpeg  | Media encoding, transcoding, muxing         |
+| ffprobe | Media file analysis and metadata extraction |
+| deno    | JavaScript / TypeScript runtime             |
+
+---
+
+## Folder structure
+
+Place the binaries exactly as shown below.  
+Do not rename them — the application resolves them by these exact names.
+
+```
+resources/
+└── binaries/

+- These binaries are excluded from version control via `.gitignore`.
+- Always use the latest stable release of each tool.

+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time.

-## 🔧 Installation
+## Overview
 
-Pour installer l'application, il vous suffit de télécharger l'installateur dans la section releases, de prendre la dernière version et de l'exécuter.
+Freedom Loader is a desktop application built with Electron that provides a straightforward way to download video and audio content with full metadata support. The application focuses on reliability, transparency, and user privacy-no ads, no tracking, no questionable third-party services.
+
+The primary goal is to make media downloading accessible to users who want offline access to their favorite content, particularly in situations where internet connectivity is unreliable or unavailable.

+
+### 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

+# Security Policy
+
+## Supported Versions
+
+Freedom Loader follows a **latest-only** support model. Security fixes are applied to the current release only — no backports to older versions.
+
+| Version       | Supported          |
+| ------------- | ------------------ |
+| Latest stable | :white_check_mark: |
+| Older versions | :x:               |
+
+I recommend always running the latest version. The built-in auto-updater will notify you when a new release is available. Older versions will not receive security patches regardless of severity.
+
+## Reporting a Vulnerability
+
+If you discover a security vulnerability in Freedom Loader, please help us keep the project and its users safe by reporting it responsibly.
+
+### How to Report
+
+**DO NOT** open a public issue for security vulnerabilities.
+
+Instead, please report security issues privately by:
+
+1. **Email**: Send details to **masteracnolo25@gmail.com** with the subject line: `[SECURITY] Vulnerability Report`
+2. **Include**:
+   - Description of the vulnerability
+   - Steps to reproduce the issue
+   - Potential impact and severity
+   - Suggested fix (if available)
+   - Your contact information for follow-up
+
+### What to Expect
+
+- **Acknowledgment**: I will acknowledge receipt of your report within 48 hours
+- **Assessment**: I will assess the vulnerability and determine its severity
+- **Updates**: I will keep you informed of our progress
+- **Resolution**: I aim to release a fix within 7-14 days for critical vulnerabilities
+- **Credit**: I will credit you in the release notes (unless you prefer to remain anonymous)
+
+## Security Best Practices for Users
+
+When using Freedom Loader, I recommend:
+
+### General Security
+
+- **Keep Updated**: Always use the latest version of Freedom Loader — older versions receive no security patches
+- **Official Sources**: Download only from official sources:
+  - [GitHub Releases](https://github.com/MasterAcnolo/Freedom-Loader/releases)
+  - [Fedora COPR](https://copr.fedorainfracloud.org/coprs/masteracnolo/freedom-loader/)
+  <!-- - [Snap Store](https://snapcraft.io/freedom-loader) -->
+- **Verify Downloads**: Check that installers are from one of the above sources
+- **Antivirus**: Keep your antivirus software up to date
+
+### Configuration Security
+
+- **Download Path**: Only set download paths within your user directory
+- **Cookies**: Be aware that Firefox cookies are used for authentication — keep Firefox secure
+- **Logs**: Logs may contain sensitive information such as URLs or local paths — avoid sharing them publicly without review
+
+### Privacy Considerations
+
+Freedom Loader respects your privacy:
+
+- **No Data Collection**: I 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 in settings
+
+## 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 outside your machine
+- **User Controlled**: You control what content you download
+
+### Native Dependencies
+
+Freedom Loader bundles the following official binaries:
+
+- **yt-dlp**: Official builds from [yt-dlp/yt-dlp](https://github.com/yt-dlp/yt-dlp) — auto-updated on each launch
+- **FFmpeg**: Official builds from [FFmpeg.org](https://ffmpeg.org/)
+- **Deno**: Official builds from [Deno.com](https://deno.com/)
+
+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 and will diminish as more users download the software.
+
+## Vulnerability Disclosure Policy
+
+### Our Commitment
+
+I am 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 directly)
+- Missing security headers on the local HTTP server (not exposed remotely)
+
+## Security Updates
+
+Security updates are released as:
+
+- **Patch Releases**: For critical security fixes (e.g., 1.6.0 → 1.6.1)
+- **Automatic Updates**: Users are notified via the built-in update system
+- **Release Notes**: Security fixes are clearly marked in the 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)

+            Under the hood, Freedom Loader bundles yt-dlp and ffmpeg directly,
+            so there is nothing extra to install: paste a link, choose a
+            format and quality, and the app handles fetching, converting
+            and tagging the file for you.
