# Description for text

How do I do add superscript[1] and add description at the end of the page? Is there any easy way?

[1] Adding description below the page and using numbers as superscripts

What you need is a \footnote.

-
more specific, write in the text \footnote{Text I want to have at the bottom}. If you are struggeling with basic LaTeX commands, have a look at an introduction such as l2short.pdf –  Martin H Jun 2 '11 at 16:47

If bonzi wants the footnote marker to be enclosed inside square brackets (which is unusual), then a redefinition of \@makefnmark will be necessary

\documentclass{article}

\makeatletter
\renewcommand\@makefnmark{\hbox{\@textsuperscript{\normalfont[\@thefnmark]}}}
\makeatother

\begin{document}

Some text\footnote{Some test footnote}

\end{document}
