+# The Serializer (Writer) Model
+
+The serializer roughly follows sections _8.1 Writing HTML documents_ and section
+_8.3 Serializing HTML fragments_ by converting DOMDocument, DOMDocumentFragment,
+and DOMNodeList into HTML5.
+
+ [ HTML5 ] // Interface for saving.
+ ||
+ [ Traverser ] // Walk the DOM
+ ||
+ [ Rules ] // Convert DOM elements into strings.
+ ||
+ [ HTML5 ] // HTML5 document or fragment in text.
+
+
+## HTML5 Class
+
+Provides the top level interface for saving.
+
+## The Traverser
+
+Walks the DOM finding each element and passing it off to the output rules to
+convert to HTML5.
+
+## Output Rules
+
+The output rules are defined in the RulesInterface which can have multiple
+implementations. Currently, the OutputRules is the default implementation that
+converts a DOM as is into HTML5.
+
+## HTML5 String
+
+The output of the process it HTML5 as a string or saved to a file.
