 ## About The Project
 
-This packages aim is to simplify programmatically generate flags to use in Unix-style command by declaring them with an object literal and turning them into an array or a string of usable flags.
+The purpose of this package is gracefully exiting Node.js processes the "good way" (opinated clearly), while also providing some minir extendability!
 
-Here's why:
-
-- You exec/spawn commands and need to provide options
-- You want to dynamically add flags without bunch of string concats
-- you don't want to have an headache refactoring when needed
+This package also takes an array of callbacks that will get executed serially to allow closing user defined resource, eg: a database connection.
