+## How to local build with nox
+
+Use separate virtual-env:
+```
+python3 -m venv venv
+source venv/bin/activate
+```
+
+Install tools:
+```
+python3 -m pip install --upgrade nox build
+```
+
+To run unit tests:
+```
+python3 -m nox -s tests-3.xx
+```
+- where `xx` is your python version, for example `10`
+
+To build package:
+```
+python3 -m build .
+```
