+Installation and Configuration
+==============================
+
+.. image:: images/python-logo-master-v3-TM.png
+
+The ResInsight Python API is compatible with `Python 3 <https://www.python.org/download/releases/3.0/>`_. 
+As admin user, the necessary Python client package is available for install via the Python PIP package system:
+
+.. code-block:: console
+
+   pip install rips
+
+or as a regular user:
+   
+.. code-block:: console
+
+   pip install --user rips
+   
+On some systems the `pip` command may have to be replaced by `python -m pip`.
+
+The ResInsight Python API is based on `gRPC <https://www.grpc.io/>`_ remote procedure calls. 
+In order for gRPC to be available, ResInsight needs to be built with the **RESINSIGHT_ENABLE_GRPC** option set. 
+A valid gRPC build will show a message in ResInsight *About* dialog confirming gRPC is available.
+
+.. image:: images/AboutGrpc.png
+
+Furthermore, gRPC needs to be enabled in the *Scripting* tab of the ResInsight *Preference* dialog:
