# Write Technical Notes with listings Package in LaTex

LaTex is an ideal tool for writing technical notes. There is even a package, named listings,  to add non-formatted text such as computer source code. This URL shows you how to use it. And, R, Python, C/C++, and Perl are all supported.

To use listing package with the beamer presentation environment of LaTex, one needs to use \begin{frame}[fragile] (note the added [fragile] option) to make it work.
