Passport process without permanent address

Hi I am new to the whole process of creating a passport and want to ask how other people who may have had a use case similar to mine went ahead with getting a passport.

My use case: I have been living on rent in Bangalore since the past 4-5 years. My family too lives on rent in Mumbai.

I mentioned this because as far as I know one needs a permanent address and address proof to submit for a passport, can someone who has dealt with a similar use case help me out please?

What should I do?
