 ### Regarding Pyinstaller
 
 As of September 2017 the Pyinstaller version on PyPi is not ready for
-Python 3.6, the developementversion is needed:
-
-~~~
-pip install https://github.com/pyinstaller/pyinstaller/tarball/develop
-~~~
+Python 3.6 and / or multiprocessing. I stopped trying to use Pyinstaller
+for distribution. The experiment is still available in the `pyinstaller`
+branch.
