\subsection{Changes}
\begin{frame}{Introduction}{Changes}
Feather theme is a great theme but after a few presentations I wanted to change colors. So using simple Hue/Saturation change I made The Red Feather Beamer Files. New files are in Feathergraphics folder. Nothing else is changed from Vankova's theme.

%-------------------------------------------------------
\subsection{Source files}
\begin{frame}{Installation}{Source files}
%-------------------------------------------------------
\begin{block}{}
The theme contains 4 source files:
\begin{itemize}
\item {\tt beamercolorthemeFeather.sty}
\item {\tt beamerouterthemeFeather.sty}
\item {\tt beamerinnerthemeFeather.sty}
\item {\tt beamerthemeFeather.sty}

\begin{frame}{Installation}{Local and Global installation}
%-------------------------------------------------------

\pause
\begin{block}{Local Installation}
\begin{itemize}
\item Local installation is the simplest way of installing the theme.
\item You need to placing the 4 source files in the same folder as your presentation. When you download the theme, the 4 theme files are located in the {\tt local} folder.
\end{itemize}
\end{block}
\begin{block}{Global Installation}
\begin{itemize}
\item If you wish to make the theme globally available, you must put the files in your local latex directory tree. The location of the root of the local directory tree depends on your operating system and the latex distribution.
\item Detailed steps on how to proceed installation under various operating systems can be found at Beamer documentation.
\end{itemize}
\end{block}

\subsection{Required Packages}
\begin{frame}{Installation}{Required Packages}
%-------------------------------------------------------
For using the Feather Theme you will need the Bemaer class installed and the following 2 packages
\begin{itemize}
\item TikZ\footnote{TikZ is a package for creating beautiful graphics. Have a look at these \chref{http://www.texample.net/tikz/examples/}{online examples} or the \chref{http://tug.ctan.org/tex-archive/graphics/pgf/base/doc/generic/pgf/pgfmanual.pdf}{pgf user manual}.}
\item calc
\end{itemize}
Due to the fact that the packages are very common they should be included in your latex distribution in the first place.
