Anyone who is experienced in working out and could help me out?

I started working out multiple times but always stopped after 1/2 months because everytime i felt like i wasnt doing the exercises the way they shouldve been done and also because i knew my calorie intake wasnt big enough for me to gain muscles. I workout at home, we have little gym in basement. Theres some dumbells there and pull up bar. Can anyone help me build some workout routine please? I could tell u exactly all of the equipment i own.
