Translation of the instruction

Unfortunately, the project was not completed. The first draft was done quickly, but not with sufficient quality. Many technical terms are incorrect, the device's purpose is described differently in various places, there are inaccuracies and inconsistencies in the text and page layout. I was forced to proofread the entire text; when I suggested asking if they did not understand the quality of the terms, they did not respond. They promised to check and correct everything, but I had to remind them several times, yet a lot of time passed and the task was still not completed. It's very disappointing because a large part of the work was done, but it was not brought to a final version.
