+
+The main way to install \CGG{} is to use the AppImage. This is updated regularly and works for every distro, since it already contains the necessary dependencies. 
+
+For 64-bit systems you can choose between an image with up-to-date libraries or one that supports older libraries, which you should use only if the first image gives you problems with unsupported libs. There is also a 32-bit older distro available that has \textit{i686} as part of the filename.  Installing the appimage is simple:
+
+Download the file from:
+
+\url{https://cinelerra-gg.org/download/images/}
+
+Some example file names are as follows - where 8 digits represent yyyymmdd:
+
+\begin{lstlisting}[style=sh]
+       CinGG-20210228-x86_64.AppImage
+         (currently based on Fedora Core 32, libc version 2.31)
+       CinGG-20210228-x86_64-older-distros.AppImage
+         (currently based on Ubuntu 16.04, libc version 2.23)
+       CinGG-20210228-i686.AppImage
+         (not yet available, but will be based on Debian 9, libc version 2.23)
+\end{lstlisting}
+
+Make the file executable with the proper execute permissions either from the GUI of the Desktop Environment used (link to the file) or from a terminal window.  Make sure you are already in the directory containing the appimage:
+
+\begin{lstlisting}[style=sh]
+       $ chmod u+x CinGG-yyyymmdd.AppImage
+\end{lstlisting}
+
+Finally start the program from a window in the directory where the image is stored:
+
+\begin{lstlisting}[style=sh]
+       $ ./CinGG-yyyymmdd.AppImpage
+\end{lstlisting}
+
+or create a convenient desktop icon with a link to the run action:
+
+\begin{enumerate}
+       \item right-click on the appimage file
+       \item Properties
+       \item Application Tab
+       \item Command:
+       \begin{lstlisting}[style=sh]
+               /path/to/appimage/./CinGG-yyyymmdd.AppImage
+       \end{lstlisting}
+       \item OK
+\end{enumerate}
+
+Most distros already have the libraries to run the appimage, but if not you may need an additional installation. For example Arch Linux needs the \texttt{libappimage} package.
+
+\begin{lstlisting}[style=sh]
+       sudo pacman -S libappimage
+\end{lstlisting}
