-\chapter{Tags}
+\chapter{Tags and Attributes}
+
+XML style tagging is used to insert functions and other behaviors into
+the script. As the document contents are output a tag may be inserted
+to perform the desired function and affect the output. 
+
+Tag attributes are used to pass parameters into the operations and
+functionality for each tag. 
+
+Outputting a database from mysql may be performed using the <mysql> tag
+in combination with the <ifrow>, <whilerow> and <sql> tags.  
+
+
+\chapter{Variables and Variable Types}
+
+
+\chapter{Expressions}
+
+Expressions are used to perform complicated calculations (arithmetic), perform
+comparisons between values (boolean), manipulate strings (string) or
+perform operations on dates (date). 
+
+\section{Functions and Operators}
+
+\subsection{left(string, number-of-characters)}
+
+\subsection{substring(string, start-position, number-of-characters}
+
+Use the substring operation to extract a portion of a string and return
+the value as a string. 
+
+\chapter{Common Gateway Interface Features}
+
+JET extension tags provides options for enabling the processing of
+data using the Common Gateway Interface (CGI) specification used by
+Apache and NGINX as well as other HTTP server applications. This makes
+JET a powerful tool for creating web interfaces and API handler
+environments for various javascript frameworks as well as just native
+HTML style interaction. 
+
+To enable the CGI features within a requested document you can specify
+the cgi="true" attribute on a <jet> tag containing the document or
+<jet /> tag contained within the document. 
+
+When you enable the CGI interface the script will look for specific
+environment variables used to retrieve the input data from the browser
+interface and automatically provide these values to the JET scripting
+using the variables interface. There are currently three supported
+data formats or content types through this interface. These content
+types are:
+
+formdata/urlencoded
+mutipart/formdata
+text/json
 
 
 
 
+\chapter{Tag Reference}
+
+This chapter will cover all the tags and parameters required to
+perform the operations that JET provides.

 \section{mysql}
 
+Use the mysql tag to specify parameters for connecting to a mysql

+statement and method of processing the result output of the executed
+sql statement. 
+
 \section{read}
 
+Use the read tag to read the contents of a file contained on the local

+a value attribute, the result of an expression (expr) attribute or the
