+Separate the construction of a complex object from its representation so that the same construction 
+process can create different representations.
 
 ## Explanation
 
 Real world example
 
-> Imagine a character generator for a role playing game. The easiest option is to let computer create the character for you. But if you want to select the character details like profession, gender, hair color etc. the character generation becomes a step-by-step process that completes when all the selections are ready.

 In plain words
 
-> Allows you to create different flavors of an object while avoiding constructor pollution. Useful when there could be several flavors of an object. Or when there are a lot of steps involved in creation of an object.

 ```java
 public Hero(Profession profession, String name, HairType hairType, HairColor hairColor, Armor armor, Weapon weapon) {
 }
 ```
 
-As you can see the number of constructor parameters can quickly get out of hand and it might become difficult to understand the arrangement of parameters. Plus this parameter list could keep on growing if you would want to add more options in future. This is called telescoping constructor anti-pattern.

 ## Applicability
+
 Use the Builder pattern when
 
-* the algorithm for creating a complex object should be independent of the parts that make up the object and how they're assembled
-* the construction process must allow different representations for the object that's constructed
