 ## Motivation
 
-Normally when we have to get logs to report the status of the applications we have to mess up many functions adding code logs.

-That makes it more difficult to test and change the dependency of the logger because we have to look for it manually in all the code.

 ## How does it work
 
-- If the module is a function the function is doctorate with the log configuration
+- Must to be the first module required in main file
+- For asynchronous functions WORKS ONLY WITH PROMISES
+- If the module is a function, the function is decorate with log configuration
 - If the module is an object(POJOs) or class instance all properties that are functions are decorated
 - If the module is a constructor function all the static methods and all the props that are functions in each instance are decorated
 - if the module is a primitive data type it does not do anything
