+/* Hello fellow developer !
+In case you are trying to add new statistics to Cuberite you need to do a few things:
+---------------------------------------------------------------------------
+1. add a new entry to the enum class Statistic in Registries\Statistics.h file
+2. add this to serialization functions in WorldStorage\NamespaceSerializer.cpp
+	The String in the above is used for saving on disk!
+	so use the same string!
 
+In case you want to add a mapping of network IDs to the used stats
+you will find a lua script in ../Tools/BlockTypePaletteGenerator/ExportStatMapping.lua
+it will provide you with information how to use it. you need a registries.json
+exported from the server https://wiki.vg/Data_Generators
