 	\begin{tcolorbox}[title=What is the societal context?]
-
+		Datacenter manageability is a top-priority for the digital society.
+		Over 3 million jobs in the Netherlands directly depend on cloud services, which are hosted in datacenters~\cite{DBLP:journals/corr/IosupKLVG22}.

 	\begin{tcolorbox}[title=What problem did we solve?]
-
+		DCDT's, still under development, lack crucial features such as predictive analytics to manage datacenters well.
+		The entire DCDT design space remains largely unexplored.
 	\end{tcolorbox}
 
 	\begin{tcolorbox}[title=How did we solve this problem?]

+		Our contributions are: a thorough literature survey with a system model, a DCDT reference architecture, and prototype-based experiments via a novel evaluation method.

 	\begin{tcolorbox}[title=Definition]
 		A DCDT mirrors the structure, context and behaviour of a datacenter~\cite{DBLP:journals/computer/AthavaleBBMMPS24}. The prerequisite to any digital twin is good monitoring and sensing capabilities in the physical entity.
