The proper technique extracts them into flashcards, but you can simply use notes. Don't read from first page to last. Jump to the part of the book you're most interested in, read that, jump to a previous chapter if there's prerequisite knowledge needed. Eventually cover the rest of the book like you'd fill out a puzzle.
Don't force yourself to learn something uninteresting. Retention is very bad and progress can get extremely slow. This is also why people who "grind leetcode" don't get very far. It's easier to instill passion than discipline. Incremental reading is one way to learn passion, as you start with the most interesting bits, which make the rest of the material slightly easier.
