@petermsouzajr in this PR, I set validations: required: true to some attributes and false to some others that you want to pay attention to. Feel free to let me know which one that you feel are required and not. I'll make the change accordingly. 😊

Please also let me know if I need to change anything (wording or anything else). Thank you!
