+
+## Steps to Create a Release
+
+This will be automated/improved in the future
+
+1. **Update version references:**
+    - [pyproject.toml](pyproject.toml): Project version
+    - [README](README.md): Version badge
+    - [CHANGELOG](CHANGELOG.md): Release details
+    - [tdm_client.py](src/wiley_tdm/tdm_client.py): API_USER_AGENT
+
+2. **Commit changes locally:**
+   ```bash
+    git commit -m "Prepare for release 1.0.0: update version references in pyproject.toml, README.md, CHANGELOG.md, and tdm_client.py"
+   ```
+
+3. **Confirm build success**
+    - [Check CI](https://github.com/WileyLabs/tdm-client/actions/workflows/ci.yml)
+
+4. **Publish to TestPyPI:**
+    - Manually run [Publish-Test](https://github.com/WileyLabs/tdm-client/actions/workflows/publish-test.yml) workflow, select Tag
+    - Confirm success
+    - Check [TestPyPI](https://test.pypi.org/project/wiley-tdm/)
+
+5. **Publish to PyPI:**
+    - Create a new GitHub [Release](https://github.com/WileyLabs/tdm-client/releases)
+    - Check [Publish](https://github.com/WileyLabs/tdm-client/actions/workflows/publish.yml) workflow (automatically triggered)
+    - Confirm success
+    - Check [PyPI](https://pypi.org/project/wiley-tdm/)
+
+## Pre-Releases
+
+Pre-releases (e.g., `1.0.0-rc1`) are used for testing purposes and are only published to TestPyPI. Follow steps 1–4 above for pre-releases, but do not proceed to step 5 (publishing to PyPI).
