-# SysML v2 Python Client
+# sysml-api-client
 
-A basic Python client library for interacting with a SysML v2 API server, specifically tested against the OpenMBEE Flexo implementation.
+A Python client for the [OMG Systems Modeling API and Services](https://www.omg.org/spec/SystemsModelingAPI), specifically tested against the OpenMBEE Flexo implementation. The PyPI name is `sysml-api-client`; Python imports remain `sysmlv2_client` and `sysml_api`.
+
+## Installation
+
+Requires Python 3.10 or newer. Once published on PyPI:
+
+```bash
+python -m pip install sysml-api-client
+```
+
+```python
+from sysmlv2_client import SysMLV2Client
+```
+
+See [RELEASING.md](RELEASING.md) for build validation and publisher setup.

+# Releasing sysml-api-client
+
+The distribution includes `sysmlv2_client` and `sysml_api`. The version comes
+from `src/sysmlv2_client/__init__.py` (initial release: `0.1.0`).
+
+## One-time setup
+
+Register a pending Trusted Publisher from your PyPI organization's **Publishing**
+page to create the project under organization ownership on the first upload.
+If you manually create the project first, add a normal Trusted Publisher to
+that project instead.
+
+| Publisher field | PyPI | TestPyPI |
+| --- | --- | --- |
+| Project name | `sysml-api-client` | `sysml-api-client` |
+| GitHub owner | `Open-MBEE` | `Open-MBEE` |
+| Repository | `sysmlv2-python-client` | `sysmlv2-python-client` |
+| Workflow filename | `publish.yml` | `publish.yml` |
+| Environment | `pypi` | `testpypi` |
+
+TestPyPI needs its own account and publisher configuration. Create GitHub
+environments `pypi` and `testpypi`; configure required reviewers for `pypi`
+and restrict it to release tags as appropriate. No PyPI token secret is needed.
+Check that PyPI accepts the project name; a pending publisher does not reserve it.
+
+References: [organization pending publishers](https://blog.pypi.org/posts/2025-11-10-trusted-publishers-coming-to-orgs/),
+[existing project publishers](https://docs.pypi.org/trusted-publishers/adding-a-publisher/).
+
+## Local validation
+
+Create and activate a virtual environment, then run:
+
+```bash
+python -m pip install -e ".[test]" build twine
+python -m pytest
+python -m build
+python -m twine check --strict dist/*
+```
+
+Start with an empty `dist/` directory. CI also tests the installed wheel outside
+the checkout, imports both packages, and builds a wheel from the source archive.
+
+## Release
+
+1. Update `__version__` and `CHANGELOG.md`; each upload needs a new version.
+2. Push the changes and wait for the test matrix and package checks to pass.
+3. Run **Publish package** manually from the desired commit to upload to TestPyPI.
+   For repeated rehearsals use new versions, such as `0.1.0rc1`, `0.1.0rc2`.
+4. In a clean virtual environment, verify the candidate (substitute its version):
+
+   ```bash
+   python -m pip install requests
+   python -m pip install --index-url https://test.pypi.org/simple/ --no-deps sysml-api-client==0.1.0
+   python -c "import sysml_api; from sysmlv2_client import SysMLV2Client"
+   ```
+
+5. Publish a GitHub release tagged `v0.1.0` at the tested commit, substituting
+   the actual version. This triggers production publishing. Approve the `pypi`
+   environment deployment if configured. The workflow rejects mismatched tags.
+6. Verify production installation in a fresh environment:
+
+   ```bash
+   python -m pip install sysml-api-client==0.1.0
+   python -c "import sysml_api; from sysmlv2_client import SysMLV2Client"
+   ```
+
+Published files cannot be replaced on PyPI or TestPyPI. Increment the version
+to correct a release.
