+#############################
+reStructured Text Style Guide
+#############################
+
+Most of the these documents are written ins reStructured Text (rst). This chapter describes some of
+the Sphinx Markup Constructs used in these documents. The Sphinx style guide can be found at:
+`Sphinx Style Guide <http://documentation-style-guide-sphinx.readthedocs.io/en/latest/style-guide.html>`_
+For a more detailed list of Sphinx Markup Constructs please refer to:
+`Sphinx Markup Constructs <http://www.sphinx-doc.org/en/stable/markup/index.html>`_
+
+This document is also an example of a directory structure for a document that spans mutliple pages.
+Notice we have the file **index.rst** and the then documents that are referenced in index.rst. The
+referenced documents are shown at the bottom of this page.
+
+A label is shown at the top of this page. Then the first construct describes a the document title
+**FD.io Style Guide**. Text usually follows under each title or heading.
+
+A **Table of Contents** structure is shown below. Using **toctree** in this way will show the headings
+in a nicely in the generated documents.
+
+.. toctree::

+Tables
+******
+
+There are two types of tables with different syntax, `Grid Tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#grid-tables>`_, and `Simple Tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#simple-tables>`_.
+
+Grid Tables
+___________
+
+`Grid Tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#grid-tables>`_ are described with a visual grid made up of the characters "-", "=", "|", and "+". The hyphen ("-") is used for horizontal lines (row separators). The equals sign ("=") may be used to separate optional header rows from the table body. The vertical bar ("|") is used for vertical lines (column separators). The plus sign ("+") is used for intersections of horizontal and vertical lines.
+
+Here is example code for a grid table in a *.rst* file:
+
+.. code-block:: console
+
+	+------------------------+------------+----------+----------+
+	| Header row, column 1   | Header 2   | Header 3 | Header 4 |
+	| (header rows optional) |            |          |          |
+	+========================+============+==========+==========+
+	| body row 1, column 1   | column 2   | column 3 | column 4 |
+	+------------------------+------------+----------+----------+
+	| body row 2             | Cells may span columns.          |
+	+------------------------+------------+---------------------+
+	| body row 3             | Cells may  | - Table cells       |
+	+------------------------+ span rows. | - contain           |
+	| body row 4             |            | - body elements.    |
+	+------------------------+------------+---------------------+
+	
+This example code generates a grid table that looks like this:
+
++------------------------+------------+----------+----------+
+| Header row, column 1   | Header 2   | Header 3 | Header 4 |
+| (header rows optional) |            |          |          |
++========================+============+==========+==========+
+| body row 1, column 1   | column 2   | column 3 | column 4 |
++------------------------+------------+----------+----------+
+| body row 2             | Cells may span columns.          |
++------------------------+------------+---------------------+
+| body row 3             | Cells may  | - Table cells       |
++------------------------+ span rows. | - contain           |
+| body row 4             |            | - body elements.    |
++------------------------+------------+---------------------+
+
+
+Simple Tables
+_____________
+
+`Simple tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#simple-tables>`_ are described with horizontal borders made up of "=" and "-" characters. The equals sign ("=") is used for top and bottom table borders, and to separate optional header rows from the table body. The hyphen ("-") is used to indicate column spans in a single row by underlining the joined columns, and may optionally be used to explicitly and/or visually separate rows. 
+
+Simple tables are "simpler" to create than grid tables, but are more limited.
+
+Here is example code for a simple table in a *.rst* file.
+
+.. code-block:: console
+	
+	=====  =====  =======
+	  A      B    A and B
+	=====  =====  =======
+	False  False  False
+	True   False  False
+	False  True   False
+	True   True   True
+	=====  =====  =======
+
+This example code generates a simple table that looks like this:
+
+=====  =====  =======
+  A      B    A and B
+=====  =====  =======
+False  False  False
+True   False  False
+False  True   False
+True   True   True
+=====  =====  =======
