## Introduction
Deskreen lets you extend or mirror your desktop to any device that has a web browser — tablets, phones, smart TVs, or unused laptops. It leverages WebRTC for low-latency peer-to-peer streaming over your local network, with no app installation required on the receiving end.

## What Deskreen Does
- Streams your entire screen or a single application window to another device
- Uses WebRTC for peer-to-peer low-latency video transmission
- Provides end-to-end encryption for all streamed content
- Generates QR codes for instant connection on mobile devices
- Works with any device that has a modern web browser

## Architecture Overview
Deskreen is an Electron-based desktop app that acts as a WebRTC signaling and streaming server. When a client connects via the generated URL, a peer-to-peer WebRTC connection is established. Screen capture uses the Electron desktopCapturer API, and the video stream is encoded and transmitted directly between peers. The Darkwire.io protocol provides end-to-end encryption.

## Self-Hosting & Configuration
- Install the application on your host computer (Windows, macOS, or Linux)
- Ensure both devices are on the same local network
- Choose to share the entire screen or a specific application window
- Adjust video quality settings based on network bandwidth
- Use the virtual display driver for a true extended desktop experience

## Key Features
- Zero-install on receiving devices: only a web browser is needed
- End-to-end encrypted streaming using Darkwire protocol
- Share full screen or individual application windows
- QR code connection for quick mobile setup
- Multi-viewer support for presentations and collaboration

## FAQ
**Q: Do I need to install anything on the receiving device?**
A: No, only a modern web browser is required on the device used as a secondary screen.

**Q: What is the latency like?**
A: WebRTC provides low-latency streaming, typically suitable for productivity tasks, though not optimized for gaming.

**Q: Can multiple devices connect simultaneously?**
A: Yes, you can share your screen to multiple browser clients at the same time.

**Q: Does it work over the internet?**
A: It is designed for local network use. Internet streaming would require additional network configuration.
