 This position paper urges decision makers in Germany to establish central RSE units within their institutions.
 Focus is not put primarily on the establishment of RSE services in general, as this has been done already elsewhere.
-Instead, motivations for especially central RSE units are discussed, underpinned by working examples both in neighbouring fields as well as outside of Germany.
+Instead, we highlight central RSE units.
+Motivations for their existance are discussed, underpinned by working examples both in neighbouring fields as well as outside of Germany.
 The heart of this paper is a vision of a central RSE unit, it's structure, and the definition of nine core support modules such a unit may provide.
 An initial survey finds that there is considerable diversity within the module distribution, even within the few considered groups.
 Initial observations on possible clusters are discussed, but need further studies.
