\documentclass{beamerikz2} % defines the document to be BeamerikZ
\begin{document}
\begin{bzFrame} % the only frame of that document
\bzOn{ % content to appear first
\bzCenter{Welcome \beamerikz!} % a centered text
}
\end{bzFrame}
\end{document}
The only file needed by the class is beamerikz2.cls that should be placed in the current directory of your *.tex file!
![[+]](/~mskrzypczak/signs//down.png){kind=small}
To upgrade from the previous version of the class, perform:
0) Replace \documentclass{beamerikz2} with \documentclass{beamerikz}
1) Find and replace in case-sensitive mode:
\bzCoords -> \bzGrid
2) Remove uses of \href
3) Move all \node, \draw, \coordinate, etc commands inside \bzOn, \bzIn, ...
4) Pay attention to flow of \bzH, \bzI, etc in content which disappears
5) Replace \bzUnder with \bzOn[-1], \bzIn[-1], etc
