Personal pool maintenance needs, what should I do?

Ive recently rented a house and it has a pool 9×5 meters, the pool, obviously he has not been used for about 2 years, but in summer this plan for the next, I know he will be clean, get the chemicals put into effect the electrical Pump and it is not, but I'm not pro in this so some advice?

You will need a test kit to monitor water concentrations of chemicals in the water. Get a professional to help you get started you some lessons you have for example, water filters and how to dope and test your pool.
