-Welcome to pygpibtoolkit's documentation!
-=========================================
+pygpibtoolkit
+=============
+
+pygpibtoolkit_ is a Python_ toolkit for talking with GPIB devices. It
+consist in a set of python modules (low-level and some more
+high-level) in order to ease writing python code to play with GPIB
+devices.
+
+There are also some utility commands and GUI tools written using this
+library (and PyQt5 for GUI tools).
+
+The aim of the project is to have an infrastructure that make it easy
+to write code to command/interact with GPIB-controlled devices, and,
+as a corrolary, make it easy to write "description" code for specific
+test equipments.
+
+Quick start
+===========
+
+The simplest way to install pygpibtoolkit_ is to use pip_. I strongly recommend
+you use virtualenvs_ for this, for example via virtualenvwrapper_ or pew_. Here
+is an example session using virtualenvwrapper_ on a Debian stretch machine:
+
+.. code-block:: bash
+
+   david@host:~$ mkvirtualenv -p /usr/bin/python3 pygpib
+   Already using interpreter /usr/bin/python3
+   Using base prefix '/usr'
+   New python executable in /home/david/.virtualenvs/pygpib/bin/python3
+   Also creating executable in /home/david/.virtualenvs/pygpib/bin/python
+   Installing setuptools, pkg_resources, pip, wheel...done.
+
+   (pygpib) david@host:~$ pip install pygpibtoolkit
+   [...]

+   Successfully installed PyQt5-5.10.1 numpy-1.14.3 pygpibtoolkit-0.1.0 pyqtgraph-0.10.0 pyserial-3.4 sip-4.19.8
+   (pygpib) david@pavo:~$ pygpib-detect --help
+   usage: A simple tool for detecting connected GPIB devices [-h] [-d DEVICE] [-v]
+
+   optional arguments:
+     -h, --help            show this help message and exit
+	 -d DEVICE, --device DEVICE
+                           Device of connected Prologix GPIB bundle
+                           [/dev/ttyUSB0]
+	 -v, --verbose

+   >>> from pygpibtoolkit.prologix import GPIB
+   >>> from pygpibtoolkit.gpibcontroller import GPIBController
+   >>> cnx = GPIB(device='/dev/ttyUSB0')
+   >>> ctl = GPIBController(cnx)
+   >>> dvm = c.register_device(24, "HP3456A")
+   >>> dvm.S0F1 # set DVM to DC Voltage mode
