How do you write a nonfiction book summary?

I always do this basic format and fill in the blanks

Point trying to get across-

Topic Sent/ Topic Paragraph/ Thesis-

Paragraph 1 (P1) Point-

P2 Point-

P3 Point-

Conclusion-

FOR THE PARAGRAPHS WRITE IN THE POINT YOU WANT TO TALK ABOUT IN EACH. Hope this helps...
