+# The Parser Model
+
+The parser model here follows the model in section
+[8.2.1](http://www.w3.org/TR/2012/CR-html5-20121217/syntax.html#parsing)
+of the HTML5 specification, though we do not assume a networking layer.
+
+     [ InputStream ]    // Generic support for reading input.
+           ||
+      [ Scanner ]       // Breaks down the stream into characters.
+           ||
+     [ Tokenizer ]      // Groups characters into syntactic
+           ||
+    [ Tree Builder ]    // Organizes units into a tree of objects
+           ||
+     [ DOM Document ]     // The final state of the parsed document.
+
+
+## InputStream
+
+This is an interface with at least two concrete implementations:
+
+- StringInputStream: Reads an HTML5 string.
+- FileInputStream: Reads an HTML5 file.
+
+## Scanner
+
+This is a mechanical piece of the parser.
+
+## Tokenizer
+
+This follows section 8.4 of the HTML5 spec. It is (roughly) a recursive
+descent parser. (Though there are plenty of optimizations that are less
+than purely functional.
+
+## EventHandler and DOMTree
+
+EventHandler is the interface for tree builders. Since not all
+implementations will necessarily build trees, we've chosen a more
+generic name.
+
+The event handler emits tokens during tokenization.
+
+The DOMTree is an event handler that builds a DOM tree. The output of
+the DOMTree builder is a DOMDocument.
+
+## DOMDocument
+
+PHP has a DOMDocument class built-in (technically, it's part of libxml.)
+We use that, thus rendering the output of this process compatible with
+SimpleXML, QueryPath, and many other XML/HTML processing tools.
+
+For cases where the HTML5 is a fragment of a HTML5 document a
+DOMDocumentFragment is returned instead. This is another built-in class.

+# 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.
