How can I create a Beamer document with a greenboard-style template like the one in the attached image? Sorry, I don't know where to start. I use this

```
\documentclass[14pt]{beamer}
\usetheme{CambridgeUS} 
\usepackage{tcolorbox}

\setbeamersize{sidebar width right=3cm}
\setbeamercolor{sidebar right}{bg=}

\makeatletter
\setbeamertemplate{sidebar right}{
  \small
  \begin{tcolorbox}[title={Notes},height=.95\textheight,width=3cm]
    \vfill%
    \beamer@tempcount=1%
    \loop%
    \hrulefill\vfill%
    \advance\beamer@tempcount by 1%
    \ifnum\beamer@tempcount<15%
    \repeat%
  \end{tcolorbox}
}
\makeatother

\begin{document}
\begin{frame}[t]
	Write something
\end{frame}
\end{document}
```
