+## Config management
+- Within the config folder each directory represents either a stack group if it has sub-directories, or an actual Cloudformation stack in case it is a leaf folder.
+- The actual configuration for each stack is hierachly merged. Lower level config files overwrite higher-level values. Complex data structures like dictionaries and arrays are deep merged.
