+# 🚀 One-Click Hugging Face Deployment
+
+## Step 1: Login to Hugging Face
+```bash
+pip install huggingface_hub
+huggingface-cli login
+```
+Enter your Hugging Face token when prompted.
+
+## Step 2: Deploy (One Command)
+```bash
+cd huggingface
+./deploy-to-hf.sh
+```
+
+## Step 3: Get Your URL
+The script will output your space URL. It will look like:
+```
+https://YOUR-USERNAME-intercept-2-0.hf.space/upload
+```
+
+## Step 4: Update iOS App
+Change this line in `ViewController.swift`:
+```swift
+guard let url = URL(string: "https://YOUR-USERNAME-intercept-2-0.hf.space/upload") else {
+```
+
+## That's it! 🎉
+
+Your GPU server will be running on Hugging Face Spaces in 5-10 minutes.

-Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+# Intercept 2.0 - 3D Gaussian Splatting
+
+Train 3D Gaussian Splats from iPhone ARKit captures using Nerfstudio.
+
+## Features
+
+- **iPhone Integration**: Works with iOS capture app
+- **ARKit Support**: Uses camera poses and LiDAR depth
+- **GPU Training**: Fast 3D Gaussian Splatting with SplatFacto
+- **Mobile Export**: Generates `.ply` files for WebGL viewing
+
+## Usage
+
+1. **Capture**: Use the iOS app to record a scene
+2. **Upload**: Send the dataset zip to this server
+3. **Train**: Server processes and trains a 3D Gaussian Splat
+4. **Download**: Get the `.ply` file for mobile viewing
+
+## API Endpoints
+
+- `POST /upload` - Upload dataset zip file
+- Returns training status and download links
+
+## iOS App Integration
+
+Update your iOS app's server URL to:
+```
+https://your-space-name.hf.space/upload
+```
+
+## Technical Details
+
+- **Framework**: Nerfstudio SplatFacto
+- **Input**: ARKit RGB + poses + LiDAR depth
+- **Output**: 3D Gaussian Splat (.ply)
+- **Training**: ~10,000 iterations (5-10 minutes)
