Khandoba is my kuldevta, Mahalasa is my kuldevi

I’m a complete beginner and I see people saying you should start by worshipping ur kuldevi and kuldevta.. how do I start? Should I start by changing ‘ shri martanda bhairavya namah’ as i did some research and khandoba is a form of martanda Bhairav.. please help me out I don’t know anything any extra information about them and their worship is welcome. Thank you so much! For context my family is not as religious the last time we visited our kul devi or devta was about 7-8 years ago we only went to the Goa mahalasa temple and havnt been to jejuri yet even though we plan to visit this year. Neither my parents nor my grand parents are actively involved in worshipping our kul devi or devta so I have no one to ask.
