Add initial setup for Fumadocs documentation migration

- Created new directory structure for documentation under `/docs2`.
- Added `.gitignore` to exclude build artifacts and dependencies.
- Introduced `package.json`, `next.config.mjs`, and `postcss.config.mjs` for project configuration.
- Implemented MDX components in `mdx-components.tsx` for rendering documentation.
- Migrated existing documentation content and created new files for auto-updater and other features.
- Established compatibility layer for Mintlify components in `mintlify-compat.tsx`.
- Set up OpenAPI documentation in `openapi.json`.
- Updated README and migration guide to reflect new structure and usage instructions.
- Ensured all components and pages are ready for development and deployment with Fumadocs.

+title: "Remote Mode"
+description: "Connect to a GPU server for faster generation"
+---
+
+## Overview
+
+Remote Mode allows you to run the Voicebox backend on a separate machine (like a GPU server) while using the desktop app on your local machine.
+
+## Use Cases
+
+- **No local GPU** - Use a cloud GPU or remote workstation
+- **Faster generation** - Leverage powerful remote hardware
+- **Shared infrastructure** - Multiple users connect to one server
+- **Laptop workflows** - Keep your laptop cool and battery-efficient
+
+## Architecture
+
+In Remote Mode, the Voicebox desktop app (running on your local machine) communicates with the backend server (running on a remote machine) via HTTP. The local app provides only the user interface, while the remote server handles all the heavy processing including the TTS models, API endpoints, and audio generation.
+
+## Setting Up Remote Mode
+
+### On the Server
+
+<Steps>
+  <Step title="Install Dependencies">
+    ```bash
+    # Clone the repo
+    git clone https://github.com/jamiepine/voicebox.git
+    cd voicebox/backend
+
+    # Install Python dependencies
+    pip install -r requirements.txt
+    pip install git+https://github.com/QwenLM/Qwen3-TTS.git
+    ```
+  </Step>
+
+  <Step title="Start the Server">
+    ```bash
+    # Allow external connections
+    uvicorn main:app --host 0.0.0.0 --port 17493
+    ```
+
+    <Warning>
+      This exposes the server to your network. Use a firewall or VPN for security.
+    </Warning>
+  </Step>
+
+  <Step title="Open Firewall">
+    ```bash
+    # Ubuntu/Debian
+    sudo ufw allow 17493
+
+    # Or use your cloud provider's firewall settings
+    ```
+  </Step>
+</Steps>
+
+### On the Client
+
+<Steps>
+  <Step title="Open Settings">
+    In Voicebox, go to **Settings → Server**
+  </Step>
+
+  <Step title="Enable Remote Mode">
+    Toggle **Use Remote Server**
+  </Step>
+
+  <Step title="Enter Server URL">
+    ```
+    http://<server-ip>:17493
+    ```
+
+    Replace `<server-ip>` with your server's IP address
+  </Step>
+
+  <Step title="Test Connection">
+    Click **Test Connection** to verify
+  </Step>
+</Steps>
+
+## Cloud Deployment
+
+### AWS EC2
+
+```bash
+# Launch a GPU instance (e.g., g4dn.xlarge)
+# Install dependencies
+# Start server with --host 0.0.0.0
+```
+
+### Vast.ai
+
+```bash
+# Rent a GPU instance
+# SSH in and clone repo
+# Start server
+```
+
+### RunPod
+
+```bash
+# Deploy a pod with CUDA support
+# Install Voicebox backend
+# Expose port 17493
+```
+
+## Security Considerations
+
+<Warning>
+  The API currently has no authentication. Only use on trusted networks or with a VPN.
+</Warning>
+
+**Best Practices:**
+- Use a VPN (WireGuard, Tailscale) instead of exposing to the internet
+- Run behind a reverse proxy with authentication (nginx + basic auth)
+- Use HTTPS with SSL certificates
+- Firewall rules to limit access to specific IPs
+
+## Performance
+
+Expected performance on various GPUs:
+
+| GPU | Generation Speed |
+|-----|------------------|
+| RTX 4090 | ~2-3s per 10 words |
+| RTX 3090 | ~3-4s per 10 words |
+| RTX 3060 | ~5-7s per 10 words |
+| CPU (12-core) | ~20-30s per 10 words |
+
+<Tip>
+  A GPU with 8GB+ VRAM is recommended for best performance.
