+# P2P Chat & File Transfer
+
+A secure, serverless peer-to-peer chat application built with Rust and iroh.
+
+## Features
+
+- **Decentralized**: No central server; peers connect directly via QUIC and NAT traversal.
+- **Commands**:
+  - `/connect <peer_id>`: Connect to a peer.
+  - `/nick <name>`: Set your display name.
+  - `/file <path>`: Send a file.
+  - `/accept <file_id_prefix>`: Accept a file transfer.
+  - `/mic`: Select microphone input.
+  - `/speaker`: Select speaker output.
+  - `/bitrate <kbps>`: Set audio bitrate.
+- **Cross-Platform**: Works on Linux, Windows, and macOS.
+  - File sharing supported on all platforms.
+  - Voice/Screen share (Linux only for now, requires PipeWire).
+
+## Installation
+
+1. Install Rust: https://rustup.rs/
+2. Clone the repo:
+   ```bash
+   git clone https://github.com/yourusername/p2p-chat.git
+   cd p2p-chat
+   ```
+3. Build & Run:
+   ```bash
+   cargo run --release
+   ```
+
+## Usage
+
+1. **Start the app**. You will see your **Peer ID** in the top bar.
+2. **Share your Peer ID** with a friend.
+3. **Connect**: Type `/connect <friend_peer_id>`.
+4. **Chat**: Type messages and press Enter.
+5. **Send Files**:
+   - Type `/file` to open a file picker.
+   - Or `/file /path/to/file` to send immediately.
+   - The recipient must type `/accept <file_id>` (or click accept if TUI supports mouse).
+
+## Configuration
+
+Configuration is stored in:
+- Linux: `~/.config/p2p-chat/config.toml`
+- Windows: `%APPDATA%\p2p-chat\config.toml`
+- macOS: `~/Library/Application Support/p2p-chat/config.toml`
+
+You can customize colors, default resolution, interface, etc.
