 ## Building the Python Package Locally
 
-The build happens through a powershell script.  You don't have to know much powershell.  
-The powershell script runs the tests using [pytest](https://docs.pytest.org/).  
-
-The package is built with [Flit](https://flit.pypa.io/).  The package will be produced in
-dist/natlinkcore-x.y.z-py3-none-any.whl.  To install it `py -m pip install dist/natlinkcore-x.y.z-py3-none-any.whl` replacing x.y with the version numbers.
-
-Normally if you are developing natlinkcore, you will with instead to install with `py -m pip install -e .`, which will
-let you make and test changes without reinstalling natlinkcore with pip.  **Note the flit install --symlink or --pth-file options are problematic so just use pip.**
-
-
-To start a powershell from the command prompt, type `powershell`.
-
-To build the package:
-
+`py -m build` to build the Python package locally.
 
-`py -m flit build`   from powershell or command prompt, which will run the the tests in natlinkcore/test, then build the the package.
-
-
-To publish the package to [The Python Package Index (PyPI)](https://pypi.org/)
-
-`publish_natlinkcore` from powershell.
-
-
- 
+Publishing to PyPi is done through the [trusted publisher mechanism](https://docs.pypi.org/trusted-publishers/using-a-publisher/) when a release is created on github using github actions. 
 
 
 ## Publishing checklist
 Before you bump the version number in __init__.py and publish:
 - Check the pyroject.toml file for package dependancies.  Do you need a specfic or newer version of
 a dependancy such as dtactions?  Then add or update the version # requirement in dtactions.  
-- don't publish if the tests are failing.   The `publish_natlinkcore` will prevent this, please don't work around it.
