+\section{Overview}
+The goal of the architecture is to facilitate an ecosystem in which an
+\gls{iTasks}-system can add, change and remove devices at runtime. Moreover,
+the \gls{iTasks}-system can send \glspl{mTask}, compiled at runtime to
+bytecode, to the device. The device runs an interpreter which can execute the
+\gls{Task}'s bytecode. Devices are persistent during reboots of the
+\gls{iTasks}-system. The methods of interacting with \glspl{mTask} is analogous
+to interacting with \gls{iTasks}-\glspl{Task}.
+
+An overview of the architecture is visible in Figure~\ref{fig:system}.

+\section{Devices}
 The client code for the devices is compiled from one codebase. For a device to
 be eligible for \glspl{mTask}, it must be able to compile the shared codebase
 and implement (part of) the device specific interface. The shared codebase only
