+Images
+------
+
+All images should be placed int he 'images' directory and referenced from the
+ReST with a relative path. This lets us shared and control images.
+
+We prefer being able to build images from source. This is not always possible
+so SVG format is preferred with generated PNG images so make sure the quality
+is consistent when building PDF output.
+
+We support the PlantUML image language. The PlantUML home page is:
+
+ http://plantuml.com/
+
+The page as a link to an 'online demo server' you can use to create images
+rathre than installing PlantUML. Save you source then View and save the PNG
+format image. The PlantUML language reference guide is:
+
+ http://plantuml.com/PlantUML_Language_Reference_Guide.pdf
+
+And the web site has online documentation. The image source extension is
+'.puml'.
+
+We also support Ditaa image language. The Ditaa home page is:
+
+ http://ditaa.sourceforge.net/
+
+The home page contain the language options. The PlantUML online demo server
+supports Ditaa so use that resource as an online tool. The Ditaa image source
+extension is '.ditaa'.
+
+You do not need PlantUML or Ditaa install to build our documentation. The
+online resources can be used. Save the source and the generated PNG file in the
+same directory under 'images'.

 Host Setup
 ----------
 
 HTML builds directly with Sphinx, PDF requires a full Latex (texlive) install,
 and building a Single HTML page requires the 'inliner' tool. The
-sphinxcontrib-bibtex extension is mandatory.
+sphinxcontrib-bibtex extension is mandatory. PlantUML requres the Node.js
+package called 'nde-plantuml' which installs the 'puml' command and Ditaa needs

+command.
 
 Please add your host as you set it up.
