+
+## Project Overview
+
+UniFace is a Python library for face detection, recognition, tracking, landmark analysis, face parsing, gaze estimation, age/gender detection. It uses ONNX Runtime for inference.
+
+## Code Style
+
+- Python 3.10+ with type hints
+- Line length: 120
+- Single quotes for strings, double quotes for docstrings
+- Google-style docstrings
+- Formatter/linter: Ruff (config in `pyproject.toml`)
+- Run `ruff format .` and `ruff check . --fix` before committing
+
+## Commit Messages
+
+Follow [Conventional Commits](https://www.conventionalcommits.org/) with a **capitalized** description:
+
+```
+<type>: <Capitalized short description>
+```
+
+Types: `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `build`, `ci`, `chore`
+
+Examples:
+- `feat: Add gaze estimation model`
+- `fix: Correct bounding box scaling for non-square images`
+- `ci: Add nbstripout pre-commit hook`
+- `docs: Update installation instructions`
+- `refactor: Unify attribute/detector base classes`
+
+## Testing
+
+```bash
+pytest -v --tb=short
+```
+
+Tests live in `tests/`. Run the full suite before submitting changes.
+
+## Pre-commit
+
+Pre-commit hooks handle formatting, linting, security checks, and notebook output stripping. Always run:
+
+```bash
+pre-commit install
+pre-commit run --all-files
+```
+
+## Project Structure

+docs/               # MkDocs documentation
+```
+
+## Key Conventions
+
+- New models: add class in submodule, register weights in `constants.py`, export in `__init__.py`
+- Dependencies: managed in `pyproject.toml`
+- All ONNX models are downloaded on demand with SHA256 verification
+- Do not commit notebook outputs; `nbstripout` pre-commit hook handles this

+## Release Process
+
+Releases are fully automated via GitHub Actions. Only maintainers with branch-protection bypass privileges on `main` can trigger a release.
+
+### Cutting a release
+
+1. Go to **Actions → Release → Run workflow** on GitHub.
+2. Enter the version following [PEP 440](https://peps.python.org/pep-0440/):
+   - Stable: `0.7.0`, `1.0.0`
+   - Pre-release: `0.7.0rc1`, `0.7.0b1`, `0.7.0a1`, `0.7.0.dev1`
+3. Click **Run workflow**.
+
+### What happens automatically
+
+The `Release` workflow:
+
+1. Validates the version string.
+2. Updates `pyproject.toml` and `uniface/__init__.py`.
+3. Commits `chore: Release vX.Y.Z` to `main`.
+4. Creates and pushes tag `vX.Y.Z`.
+
+Pushing the tag then triggers:
+
+- **Publish to PyPI** — builds the package, runs tests on Python 3.10–3.14, uploads to PyPI, and creates a GitHub Release (flagged as pre-release for `a`/`b`/`rc`/`.dev` versions).
+- **Deploy docs** — fires only after a **stable** GitHub Release is published. Pre-releases do not update the live documentation site.
+
+### Verifying a release
+
+- PyPI: <https://pypi.org/project/uniface/>
+- GitHub Releases: <https://github.com/yakhyo/uniface/releases>
+- Docs (stable only): <https://yakhyo.github.io/uniface/>
+
+### Installing a pre-release
+
+End users can opt in to pre-releases with the `--pre` flag:
+
+```bash
+pip install uniface --pre                # latest pre-release
+pip install uniface==0.7.0rc1            # specific pre-release
+```
+
+Without `--pre`, `pip install uniface` always resolves to the latest stable version.

 ## Design Principles
 
-### 1. ONNX-First
+### 1. Cross-Platform Inference
 
-UniFace runs inference primarily via ONNX Runtime for core components:
+UniFace uses portable model runtimes to provide consistent inference across macOS, Linux, and Windows. Most core components run through ONNX Runtime, while optional components may use PyTorch where appropriate.
 
 - **Cross-platform**: Same models work on macOS, Linux, Windows
 - **Hardware acceleration**: Automatic selection of optimal provider
 - **Production-ready**: No Python-only dependencies for inference
 
-Some optional components (e.g., emotion TorchScript, torchvision NMS) require PyTorch.
-
 ### 2. Minimal Dependencies

+## Upgrading
+
+When upgrading UniFace, stay consistent with your runtime extra:
+
+```bash
+pip install --upgrade uniface[cpu]   # or uniface[gpu]
+```
+
+If you are switching from CPU to GPU (or vice versa):
+
+```bash
+pip uninstall onnxruntime onnxruntime-gpu -y
+pip install uniface[gpu]   # install the one you want
+```
+
+---
+
+## Pre-release Versions
+
+UniFace ships release candidates and betas to PyPI ahead of stable releases (versions like `0.7.0rc1`, `0.7.0b1`, `0.7.0a1`). These let you try upcoming features before they're finalized.
+
+`pip install uniface` always installs the latest **stable** release. To opt in to pre-releases:
+
+```bash
+# Latest pre-release (if newer than latest stable)
+pip install uniface[cpu] --pre
+
+# A specific pre-release
+pip install uniface[cpu]==0.7.0rc1
+```
+
+Pre-releases are not recommended for production — APIs may still change before the stable release.
+

 ## Troubleshooting
 
+### onnxruntime Not Found
+
+If you see:
+
+```
+ImportError: onnxruntime is not installed. Install it with one of:
+  pip install uniface[cpu]   # CPU / Apple Silicon
+  pip install uniface[gpu]   # NVIDIA GPU (CUDA)
+```
+
+You installed uniface without an extra. Run the appropriate command above.
+
+---
+
+### Both onnxruntime and onnxruntime-gpu Installed
+
+If you previously ran `pip install uniface[gpu]` on top of a `pip install uniface[cpu]`
+(or vice versa), you may have both packages installed simultaneously, which causes conflicts.
+Fix it with:
+
+```bash
+pip uninstall onnxruntime onnxruntime-gpu -y
+pip install uniface[gpu]   # or uniface[cpu]
