+These chapters are based on our experiences with using specific software technologies.
+
+The main audience is RSEs familiar with basic computing and programming concepts.
+
+The purpose of these chapters is for someone unfamiliar with the specific technology to get a quick overview of the most important concepts, practices and tools, without going into too much detail (we provide links to further reading material for more).
