+If using a compiled build (that is, NOT an AppImage) to add true type fonts, copy the \texttt{.TTF} files to the fonts directory at \texttt{/usr/lib/cinelerra/fonts}
+or if not system installed, at \texttt{<cinelerra\_install\_path>/bin/plug\-ins/fonts}. In that directory run
+\vspace{1ex}
+\begin{lstlisting}[style=sh]
+ # /usr/lib/cinelerra/fonts
+ ttmkfdir && mv fonts.scale fonts.dir
+\end{lstlisting}
+and restart \CGG{}. The new fonts should appear. However, keep in mind that the next
+time you install a new version of CINELERRA-GG, your changes will be written over so
+you will have to make sure to save them elsewhere and then re-establish.
+The usage of ttmkfdir changes frequently so this technique might not work. The titler supports mainly \textit{TTF}, true type fonts. It supports others such as OTF, but TTF are the most reliable.
+
+AppImage does not provide this specific method unless you use the workaround as described in the Appendix \nameref{cha:faq_problems_workarounds}.
+However, if you use Ubuntu Studio 2304 with AppImage, you can easily add font files directly to ~/.fonts and you will have all of these available in the Title fonts list. And, there may be other operating systems with specific implementations that also allow for this easier methodology to add additional fonts.
+
+Some of the system fonts are automatically included in the set of fonts being used by \CGG{}. The easiest way to add additional system or other application available fonts for the Title plugin's set, is to use ones available in specific directories on your computer as long as they have a \texttt{fonts.scale} file already set up. You can run \texttt{mkfontscale} to create this file within that directory. In order to include a specific directory you set an environment variable before starting \CGG{} which stays in effect until it is unset or until the next reboot. Below is the method and an example.
