+controls-py is a simple SCADA system
+
+Supervisory control and data acquisition (SCADA) systems are control systems designed to manage network data flow
+between different sources, such as computers, sensors and controllers, providing a convenient interface for
+high-level supervision of processes. Typical problems SCADA systems are aimed at are:
+
+* Data acquisition
+* Data communication
+* Data presentation
+* Remote control
+* Statistics collection
+* Alarm handling
+
+Modern SCADA systems offer new, advanced features, that became de-facto standard today:
+
+* Scalability. Modern SCADA systems are more scalable than legacy systems for several reasons, including better availability of supported hardware and software and use of cloud computing to meet workload demand.
+* Interoperability. Legacy SCADA systems rely on proprietary hardware and software, resulting in vendor lock-in.
+* Communications. Modern SCADA systems support more widely supported and modern communications protocols, which enable greater accessibility to SCADA data and controls.

+Usage
+=====
+
+Install a development environment
+---------------------------------
+
+To create a dev environment, first install virtualenv. You may use pip
+
+.. code-block:: console
+
+   $ pip install virtualenv
+
+Or use your system package manager, for example, pacman in Arch-based distributions:
+
+.. code-block:: console
+
+   $ pacman -S virtualenv
+
+Then create an empty environment and enter it:
+
+.. code-block:: console
+
+   $ virtualenv path/to/env
+   $ source /path/to/env/bin/activate
+
+Finally, install dev requirements:
+
+.. code-block:: console
+
+   (env) $ pip install -r requirements.txt
+
