 ====================
 
 Use a docx as a jinja2 template
+
+Introduction
+------------
+
+This package uses 2 major packages :
+
+- python-docx for reading, writing and creating sub documents
+- jinja2 for managing tags inserted into the template docx
+
+python-docx-template has been created because python-docx is powerful for creating documents but not for modifying them.
+
+The idea is to begin to create an exemple of the document you want to generate with microsoft word, it can be as complex as you want :
+pictures, index tables, footer, header, variables, anything you can do with word.
+Then, as you are still editing the document with microsoft word, you insert jinja2-like tags directly in the document.
+You save the document as a .docx file (xml format) : it will be your .docx template file.
+
+Now you can use python-docx-template to generate as many word documents you want from this .docx template and context variables you will associate.

+
+Jinja2-like syntax
+------------------
+
+As the Jinja2 package is used, one can use all jinja2 tags and filters inside the word document.
+Nevertheless there are some restrictions and extensions to make it work inside a word document:
+
+Restrictions
+++++++++++++
+
+The usual jinja2 tags, are only to be used inside a same run of a same paragraph, it can not be used across several paragraphs, table rows, runs.
+
+Note : a 'run' for microsoft word is a sequence of characters with the same style. For exemple, if you create a paragraph with all characters the same style :
+word will create internally only one 'run' in the paragraph. Now, if you put in bold a text in the middle of this paragraph, word will transform the previous 'run' into 3 'runs' (normal - bold - normal).
+
+Extensions
+++++++++++
+
+Tags
+....
+
+In order to manage paragraphs, table rows, runs, special syntax has to be used ::
+
+   {%p jinja2_tag %} for paragraphs
+   {%tr jinja2_tag %} for table rows
+   {%r jinja2_tag %} for runs
+
+By using these tags, python-docx-template will take care to put the real jinja2 tags at the right place into the document's xml source code.
+In addition, these tags also tells python-docx-template to remove the paragraph, table row or run where are located the begin and ending tags.
+
+Display variables
+.................
+
+As part of jinja2, one can used double braces::
+
+   {{ <var> }}
+
+But if `<var>` is an RichText object, you must specify that you are changing the actual 'run' ::
+
+   {{r <var> }}
+
+Note the 'r' right after the openning braces
+
+Cell color
+..........
+
+There is a special case when you want to change the background color of a table cell, you must put the following tag at the very beginning of the cell ::
+
+   {% cellbg <var> %}
+
+`<var>` must contain the color's hexadecimal code *without* the hash sign
+
+Escaping
+........
+
+In order to display `{%`, `%}`, `{{` or `}}`, one can use ::
+
+   {_%, %_}, {_{ or  }_}
