The first two pages of the link above outlines everything that needs to be included while filing N-400. Just submit what documents apply to you and your situation. When you file online, it’ll ask you to upload specific documents based on your answers (for ex: if you say you’ve been arrested, it will ask you to upload court records).  Also, you don’t have to complete and submit the application in one sitting so you can go back to it if you’re missing a document at the moment. I believe once you start it, you have 30 days to submit. Otherwise you’ll have to start the application all over again. You pay at the end once you submit the application, so it’s not like you’ll be charged multiple times if you have to restart because you didn’t finish in 30 days. 

You have held a greencard five years. You do not need to prove anything about the legitimacy of your former marriage. Include nothing of the sort. No marriage certificate, no joint bank accounts, no joint leases. You are not gaining citizenship early (3 years) as a perk because of being married to a USC. You are simply qualifying for citizenship all by yourself because you have been a permanent resident for five years. 
 
All you have to do is answer any  biographical information asked for on the form  like marital status and info on current spouse and former spouses.

You are eligible to be a citizen on 7/27/2017 so can apply at any time
That is [date of first card] + [five years]
 
You may even progress faster than others applying in the same month because they often apply 90 days before eligibility so they normally have to get past their date before interview.  You are already past your eligibility date so can move on through to interview and oath as quick as your office can process you. 

for those 3-year-rule applicants, do they have to maintain the marriage alive during the 3 years before filing N400 ?
 
i know some folks got married to USC for green card purpose only, then jumped out of the marriage. 
 
This is a big concern when people like this file for citizenship. the officers will definitely have questions regarding to your marriage that failed and even doubt your motivation for green card. ...." fake marriage“ ！Reg flag of course !
 
Dont let the officer think you are cheating in the marriage and immigration.

Anybody who has had a greencard for 5 years can apply for citizenship. They do not have to be married or prove a marital relationship. 
 
Anybody who has had a greencard for 3 years that they got because they married a US citizen, can apply for citizenship if they are still married to the same USC. Their application must include evidence of their continued marital relationship.
