% LaTeX Beamer template for PSI
% the format is  16:9 

% Compile with LuaTex or XeTex, because you need the Aptos-Font
% If you use Overleaf, you have to change the compiler (https://www.overleaf.com/learn/how-to/Changing_compiler)

% The folder "Aptos"  with the Aptos font is required if you do not use a Windows PC, for example, by using the online LaTeX editor Overleaf.

% Things where you may adapt are with %%%
