How do you annotate a textbook?
Preview the chapter, read one section, then mark only what matters: underline key terms and definitions, write a one-line summary in the margin, and put a question mark where you are lost. Use a simple code of symbols or colors, annotate sparingly, and finish each chapter with a short summary in your own words.

In more detail
Annotating is active reading. The point is not a colorful page, it is a trail you can review later. Highlighting whole paragraphs feels busy but teaches little. Mark only the few phrases that carry the point, and write more than you highlight.
Pick a system before you start and keep it for the whole book. For example: underline definitions, circle names and dates, star what is likely to be on the exam, write a question mark next to anything unclear, and number the steps of a process. Write the key to your code on the first page.
Paper or PDF, the system is the same. In a PDF reader use the highlight and comment tools, which also makes your marks searchable. With a paper book, a pencil and small sticky flags keep the page readable.

More questions
Should I highlight or underline a textbook?
Either, as long as you do it sparingly and add words. Highlighting alone does little for memory. Notes in your own words and questions do more.
How do I annotate a PDF textbook?
Use the highlight and comment tools in a PDF reader, with the same symbols or colors you would use on paper. Keep comments short and review them chapter by chapter.
What do I do with my annotations afterwards?
Turn them into questions. Starred items and margin questions make good flashcards, and the one-line summaries make a quick review sheet.
