+# - dist/deltaglider-0.1.0-py3-none-any.whl (wheel)
+```
+
+## Test with TestPyPI (Optional but Recommended)

+1. Upload to TestPyPI:
+```bash
+python -m twine upload --repository testpypi dist/*
+```
+
+2. Test installation:
+```bash
+pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ deltaglider
+```

+
+```bash
+# Upload to PyPI
+python -m twine upload dist/*
+
+# You'll be prompted for:
+# - username: __token__
+# - password: <your-pypi-api-token>
+```
+
+## Verify Installation
+
+```bash
+# Install from PyPI
+pip install deltaglider
+
+# Test it works
+deltaglider --help
+```
+
+## GitHub Release
+
+After PyPI release, create a GitHub release:
+
+```bash

+git push origin v0.1.0
+```
+
+Then create a release on GitHub:

+1. Update version in `pyproject.toml`
+2. Update CHANGELOG
+3. Commit changes
+4. Follow steps above
+
+## Automated Release (GitHub Actions)
+
+Consider adding `.github/workflows/publish.yml`:
+
+```yaml
+name: Publish to PyPI
+
+on:
+  release:
+    types: [published]
+
+jobs:
+  publish:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v4
