+pyrandr
+=======
+
+``pyrandr`` is a small wrapper on ``xrandr`` to provide most common usage as
+simple as possible.
+
+Requirements
+------------
+
+``pyrandr`` doesn't require any other thing than python and ``xrandr`` command
+line tool. Currently it is tested only on Python2.7, support for Python3 is
+coming.
+
+Installation
+------------
+
+Just make ``pyrandr.py`` executable and drop somewhere in your ``$PATH``.
+
+Usage
+-----
+
+Invocation is simple, executing the script:
+
+.. code:: shell-session
+
+   user@localhost $ pyrandr.py
+
+should list all mailable outputs for your display device(s)
+
+Use ``--help`` to see all the other options:
+
+.. code:: shell-session
+
+   (myenv)user@localhost ~/mylogs $ pyrandr.py -h
