-For Linux and generally, ``gmic-py`` can be installed for Python >= 3.6 using:

-    pip install gmic

-MacOS works the same but needs `libomp` on top.
-Windows will be supported in the third quarter of 2020.

+Here is how to install the ``gmic-py`` binary Python module on your operating system.
+
+For now only Mac OS (till 2.8.3) and Linux / Unix (2.9.x) are supported.
+
+For ``sp`` / ``sample`` and ``update`` commands to work, the `curl <https://curl.se/>`_ executable must be installed (highly likely).
+
+If you cannot install anything on your machine, you may also install ``gmic-py`` from a Jupyter Notepad or Google Colab, see :doc:`jupyter`

 For desktop UI implementations such as `Jupyter QtConsole <https://jupyter.org/qtconsole/stable/>`_, since your operating systems' `DISPLAY` environment variable is set, above point 1. is still relevant, but the G'MIC native display will probably pop up instead of the `PNG` trick.
