+## Instructions for building and uploading FoBiS.py to PyPi
+
+### Prepare before build
+
+In `release` branch, bump verion number in `src/main/python/fobis/FoBiSConfig.py`, e.g. `__version__ = "3.0.6"`.
+Commit the file changed.
+
+### Build
+
+In repo root type
+
+```bash
+pyb
+```

+This creates a `release/FoBiS-release-v3.0.6/` directory, build the package and test it.
+
+If `pyb` is not installed, install it via pip
+
+```bash
+pip install pybuilder
+```
+
+### Upload the package to PyPi
+
+Enter release directory, prepare the package distribution and upload it:
+
+```bash
+cd release/FoBiS-release-v3.0.6/
+python setup.py sdist
+twine upload dist/*
+```
+
