Documentation Build Instructions
################################

The `website documentation`_ for Clear Linux\* OS for Intel Architecture
should be written in :abbr:`ReStructuredText (ReST)` AKA ``.rst``, which
makes it easy to build parsable, command-line readable, indexed, and
search-friendly documentation and APIs with `Sphinx`_.

.. _requirements:

Requirements
============

To build documentation with Sphinx, ensure your system has these
prerequisites:

* `GNU make`_
* `Python`_
* `PIP`_
* `Sphinx`_

The instructions for installing these varies according to OS. On a basic out-
of-the-box Ubuntu-like OS (which usually has Python installed by default),
check your python version you might need something like:

.. code-block:: console

   $ sudo apt-get install python-pip
   $ sudo pip install -U sphinx sphinx-autobuild



.. code-block:: console

   $ python -c 'print __import__("sphinx").__version__'
     1.3.1

Cloning the documentation repository
====================================

We have confirmed Sphinx installed.  The next step is to clone Gitlab
repository to our local machine.


.. code-block:: console

   $ git clone https://github.com/clearlinux/clear-linux-documentation

Run make
========

Finally are we ready to run :command:`make`. Be sure to :command:`cd` to the
:file:`source/` directory where your ``.rst`` files are, before
running :command:`make html`, or the doc format of your choice.

.. code-block:: console

   $ make html
   >
   sphinx-build -b html -d _build/doctrees   . _build/html
   Running Sphinx v1.3.1
   making output directory...
   .
   .
   .
   build succeeded, 0 warnings.

   Build finished. The HTML pages are in _build/html.

Open one of the .html pages in a web browser to view the rendered
documentation.

needed to integrate beautifully on the clearlinux.org website, please see
