Good afternoon!
It is necessary to proofread and edit the text for the book. Correct errors, improve formulations if necessary. The meaning of the text must not be changed in any way, and no additional information that is not discussed should be invented. Everything must be left exactly as it is, without distorting the meaning and without adding non-existent information to the text, i.e., without arbitrary invented additions. However, the text can be improved with formulations that could be expressed more concisely, clearly, correctly, and "beautifully," without distorting the meaning itself. The accuracy of the original meaning is important; the meaning cannot be changed, and what is written must be followed absolutely accurately with the meaning of the text. (You can suggest options if you want to improve something in particular and communicate separately options for overall improvement).
Repetitions of the same words or phrases in sentences (if any) can be slightly diversified with definitions that are similar in meaning but sound more "solid" and are formulated differently.
All changes to the text, including punctuation, must be highlighted with some color background.
The most important thing is to find and correct errors, prepare the text so that it can be published in this form.
