 ## Developers Instructions
 1. every push to the casaconfig repository will push a new wheel to [test pypi](https://test.pypi.org/project/casaconfig/#history)
-2. the version in setup.py must be updated before each push so that the wheel has a unique name (e.g. "1.2.3dev2", where "dev?" could be incremented during development)
+2. the version in pyproject.toml must be updated before each push so that the wheel has a unique name (e.g. "1.2.3dev2", where "dev?" could be incremented during development; see the [specification](https://packaging.python.org/en/latest/specifications/version-specifiers/#version-specifiers) for more information about valid version signifiers)
 3. When testing with a casatools build, "pip install" the development casaconfig wheel before running any tests - it may be installed before casatools is installed or after since the casatools build does not depend on casasconfig (uninstall any already installed casaconfig if necessary).
 4. For release, follow the above instructions.
+
+Wheels can be built locally following the same process used by the CI actions. To install the build-system dependencies as defined in pyproject.toml and then generate a source distribution and wheel:
+```
+python3 -m pip install build setuptools --user
+python3 -m build
+```
+This will create:
