-This repository contains instructions to generate UN/LOCODE database for FrostFS
+FrostFS uses UN/LOCODE in storage node attributes and storage policies. Inner
-and raw representation of it. FrostFS uses UN/LOCODE in storage node attributes
+ring nodes converts UN/LOCODE into human-readable set of attributes such as
