Good Detailed Resources For Terrace Garden Creation

Question

Two small slope areas but I want to do it right, so I only have to do it once. Youtube vidoes do not seem quality enough or lack details and appear more about getting a person to hire someone instead of giving full instructions. Good info resource needed. Thanks
