How to add complementary foods for children

Patient's question:

My daughter just turned 4 months old, and it's the right time to start adding complementary foods. I bought Heng-style for her. I'd like to ask how many times a day should she eat it at the beginning, how much per meal, and how to prepare it properly? Thank you
