-The package \pkg{pst-exa} was created to realize examples with printed code and output
-side by side or on top of each other. The package looks in the image directory for the source
-code of the examples and inserts only the code between the environment \env{document},

+\tableofcontents
 
-The package provides the environment \env{PSTexample} with the optional
-arguments. For more information read the documentation of \texttt{pst2pdf}.
+\clearpage
 
-Using \pkg{pst-exa} makes only sense together with the Perl script \texttt{pst2pdf}, which
-allows the use of Postscript code and running the document in \textsc{pdf} mode.
+\section{Introduction}
 
-\nocite{*}
-\bibliographystyle{plain}
-\bibliography{\jobname}
+The package \LPack{pst-exa} was created to realize examples with printed
+code and output side by side or on top of each other. The package
+looks in the image directory for the source code of the examples
+and inserts only the image for code environment
+
+However, creating a \PDF\ file in a direct way with \Lprog{pst2pdf} or \Lprog{ltximg} is
+possible and the compiles whits \Lprog{pdflatex}. 
+
+\PST\ as \PS\ related package uses the programming language \PS\ for internal
+calculations. This is an important advantage, because floating point arithmetic is no
+problem. Nearly all mathematical calculation can be done when running the \DVI-file
+with \gs. 
+
+\section{Loading the package}
+
+The package \LPack{pst-exa} must be loaded with one of the following options in the preamble of the document:
+
+\begin{verbatim}
+\usepackage[swpl]{pst-exa}
+\end{verbatim}
+
+automatically load \LPack{showexpl} package. 
+
+\begin{verbatim}
+\usepackage[tcb]{pst-exa}
+\end{verbatim}
+
+automatically load \LPack{tcolorbox} package.
+
+\section{Environments}
+The package \LPack{pst-exa} provides two environments:
+
+\Lenv{PSTcode} to write only code that does not generate 
+an image, this is necessary to not interrupt the order in which the images are copied by the script in the process 
+of conversion to pdf. 
+
+\Lenv{PSTexample} environment,
+to write only code that generates an image, keep in mind that the script that performs the extraction process 
+does not distinguish the format given to the lines in this environment (only reads plain text) the idea is to 
+concentrate on the image you want to extrare and then in the format of the text.
+
+\section{Programs needed}
+You need \nxLprog{pst2pdf} (or \Lprog{ltximg}) whit a latest version of \Lprog{Ghostscript} (9.14), 
+\Lprog{perl} (>=5.18), \Lprog{pdf2svg}, \Lprog{pdftoppm} and \Lprog{pdftops}
+(from \Lprog{poppler-utils} or \Lprog{xpdf-utils}) for the process file. 
+
+The general syntax for the \emph{script} is simple:
+
+\begin{BDef}
+\nxLprog{perl} \nxLprog{pst2pdf} \Larg{file.tex} \Largs{--options}
+\end{BDef}
+
+For \TeX Live users:
 
+\begin{BDef}
+\nxLprog{pst2pdf} \Larg{file.tex} \Largs{--options}
+\end{BDef}
+
+this create file-pdf-exa.pdf and file-fig-exa-1.pdf, file-fig-exa-2.pdf, file-fig-exa-\dots.pdf
+
+\section{Examples with option \texttt{tcb}}
+
+\verb|\begin{pspicture}| o \tcboxverb{\begin{pspicture}[showgrid](4,4)}
+
+\begin{pspicture}[showgrid](4,4)
