\frametitle{How to use it}
\framesubtitle{How to install it to your path}
\begin{itemize}
\item Place the contents within your TEXINPUTS path. On Linux, modify the TEXINPUTS variable to point to the directory where these files exist.
\item For example: \lstinline[language=bash]|export TEXINPUTS=${HOME}/LaTeX//:${TEXINPUTS}|
\item On MacTeX, you need to install it to \lstinline|${HOME}/Library/texmf/tex/latex/sussexdark|
\item If you have admin permission copy it to your \TeX{} tree to the directory where the other beamer themes are located e.g. \lstinline|/usr/share/texmf-texlive/tex/latex/beamer/themes|
\item To use the theme, add the command \lstinline[language={[LaTeX]TeX}]|\usetheme{sussexdark}| to the preamble of your document.
\item Compile using pdflatex to get the pdf file.
\item Feel free to modify the theme to suit your needs.
