how to make the pdf, or how to put it onto your website?
to make a pdf, you can use either adobe's professional pdf maker, or free programs like LaTeX-compatible programs and OpenOffice let you export to pdf for free.
to get it onto your website, just use the buttons to insert a link like you normally do, but link it to the pdf file. or in the html, add this:
<a target='_blank' href="your_pdf_here.pdf">click to see the pdf file</a>
