\chapter{VILLASnode structs\label{a:villas_structs}}
This appendix presents a few structures which help to understand the VILLASnode architecture from \autoref{chap:architecture}. A full overview of all header files can be found on the VILLASnode Git repository\footnote{\url{https://git.rwth-aachen.de/acs/public/villas/VILLASnode}}.
