+# HuggingFace ONNX
+
+Tool for discovering, downloading, and validating ONNX models from HuggingFace.
+
+## Extra Dependencies
+
+```bash
+pip install huggingface_hub pyyaml requests onnx onnxruntime numpy
+```
+
+## Huggingface Manager (discovering and downloading)
+
+The `huggingface_manager.py` script discovers top ONNX models from HuggingFace, collects metadata, and optionally downloads them.
+
+```bash
+# Download top 50 models sorted by downloads
+python huggingface_manager.py --limit 50 --download
+
+# Just collect metadata (no download)
+python huggingface_manager.py --limit 100
+
+# Sort by likes instead of downloads
+python huggingface_manager.py --limit 20 --sort likes --download
+
+# Custom output file
+python huggingface_manager.py --limit 10 --output my_models.yaml
+```
+
+### Output Format
+
+The tool generates a YAML file with the following structure:
+
+```yaml
+repositories:
+  "model-name":
+    url: "https://huggingface.co/model-name"
+    download_path: "/path/to/models/..."  # when --download used
+    files:
+      - file: "model.onnx"
+        size: "90.91MB"
+total_size: "2.45GB"
+created_at: "2024-01-15T10:30:00Z"
+```
+
+## Run Models (validation)
+
+The `run_models.py` script validates ONNX models against ONNX Runtime for correctness.
+
+```bash
+# Validate models from a YAML configuration file
+python run_models.py --validate huggingface_repos.yaml
+
+# Debug specific repository (downloads and validates all ONNX models)
+python run_models.py --debug sentence-transformers/all-MiniLM-L6-v2
+
+# Debug specific model file
+python run_models.py --debug sentence-transformers/all-MiniLM-L6-v2/onnx/model.onnx
+
+# Debug with model truncation for debugging and validating intermediate results
+DEBUGONNX=1 python run_models.py --debug sentence-transformers/all-MiniLM-L6-v2/onnx/model.onnx --truncate 10
