The project brought the right result, but I will not say that it was easy. From my side, the directions were not the most clear, but when I turn to a professional, I expect that he knows more of me and will tell me what and how to do better, especially in writing texts. At the end, the introduction of the straight was quite at the level of copypaste, i.e. Not to make the text perfect with the direction that was indicated, but to banal copying my same correction options with my same comments in scratches.
