Hello Nihal, the documents will verify manually at the centers allocated to you. Before going for document verification candidate have to register for document verification. You can register by going your user portal by using your login id and password. Keep original documents with 1 xerox copy with you. Documents will be verified against the information you have entered while filling application form. 

It is necessary to keep aadhar card or any other ID proof while going to Document verification.

I hope it will help.

Thanks.
