 `set` is a data structure package written by **Go**. It provides some basic set functionalities of the user. It uses 
-`map` data structure under the hood. It does not have any dependency. 
+`map` data structure under the hood.

+* Written in vanilla Go with no dependency.
+* Supports thread-safety.
+* Two different set options. Thread-safe and Thread-unsafe.
+* Supports any data type(integer, float, string, byte, and so on).
