+=== Three new attributes: Salary, Occupation, Relationship
+==== Current Implementation
+The add Command is modified in this enhancement. Previously, user can only add a person's name, phone number, address and tags to the address book.
+After this enhancement, following attributes are added to the person's information:
+
+* `SALARY`: salary must be a string with more than one digits
+* `OCCUPATION`: occupation can be a string with any characters
+*  `RELATIONSHIP`: relationship must be a string with one word (no blank allowed)
+
+===== How to implement the command
+Users just input:
+add n/NAME p/PHONE e/EMAIL a/ADDRESS s/SALARY o/OCCUPATION r/RELATIONSHIP [t/TAG]
+Example: add n/John Doe p/98765432 e/[email protected] a/311, Clementi Ave 2, #02-25 s/100000o/bankerr/singlet/friends t/owesMoney

+
+===== Pros and Cons
+** Pros: Easy to implement, and the add format just follows the previous version
+** Cons: When implementing add Command, Users must add all information except the optional TAG attribute, this makes the command not flexible enough
