-# PIP packaging instructions
-TL;DR;
+# Packaging instructions (uv)
+
+We use [uv](https://docs.astral.sh/uv/) for building and publishing.
+
+TL;DR:
 
 ```bash
-python -m pip install --upgrade build wheel twine
-python -m build && python -m twine upload dist/*
+uv build && uv publish
 ```
 
+`uv build` produces the sdist and wheel in `dist/`. `uv publish` uploads them to PyPI.
+
+Authentication for `uv publish` (use a PyPI API token):
+
+```bash
+uv publish --token <pypi-token>
+# or via environment variables
+export UV_PUBLISH_TOKEN=<pypi-token>
+uv publish
+```
 
 JLAB CERTIFICATE ERROR:
 
+If you hit an SSL certificate error behind the JLab network, point uv at the JLab CA bundle:
+
 ```bash
-python -m twine upload --cert /home/romanov/JLabCA.crt dist/*
+export SSL_CERT_FILE=/home/romanov/JLabCA.crt
+uv publish
 ```
