Just bought house and started renting this year - what to do?

Hi I bought a home in January this year , paid for some updates and rented it out in May (located in Tennessee).  What should I do to prepare for the upcoming tax filing season? This is my first year as a landlord - how do I prepare myself for real estate depreciation, deductions and lowering my tax ? Should I request any sort of documents besides the receipts from my contractors? Thanks!
