How to apply for Re-Entry permit??

[Rama3265]

Hi All-
I have greencard and planning to travel India for more than 6 months for personal reasons. I would like to apply for re-entry permit for the first time and would like to know if anybody have the list of documents to file 1-131. Any information is appreciated.
Regards
Rama
