📚 Problem

The current README is missing crucial setup instructions for downloading the ResNet18 ONNX model, which is required for building the project. Users attempting to build would encounter failures due to the missing model file.

🔧 Solution

Added Clear Setup Instructions

• Step-by-step ResNet18 ONNX model download from official ONNX model zoo
• Models directory creation command (mkdir -p models)
• Download verification step to confirm successful download (~45MB file)
• Updated section numbering to maintain proper sequence

New Quick Start Flow

1. Clone and Setup
2. Download ResNet-18 ONNX Model ← NEW
3. Build with ONNX Support
4. Generate Test Data
5. Start the Server
6. Test the API

📋 Changes

README.md Updates

• Added comprehensive ResNet18 ONNX download instructions
• Included curl command to download from official ONNX model zoo
• Added file size verification (should show ~45MB resnet18.onnx)
• Updated all subsequent section numbers to maintain sequence

User Experience Improvements

• ✅ Clear prerequisite setup before building
• ✅ Official ONNX model zoo source (trusted)
• ✅ Verification step to confirm successful download
• ✅ No more mysterious build failures due to missing models

🎯 Expected Results

After this PR:

• ✅ New users can successfully build the project on first try
• ✅ Clear understanding of ONNX model requirements
• ✅ No confusion about where to get the ResNet18 model
• ✅ Proper setup flow that matches the actual build process

This resolves the gap in documentation that could cause frustration for new users trying to get started with Furnace.
