- clone 'kino' folder into any path you want
- load unpacked extension in chrome via Extensions/Developer Mode
- read https://developer.chrome.com/extensions/getstarted for more details
- export works if it least 2 pages with movies found on kinoestet.ru
- kinopoisk.ru could block you marks functionality for you if you submit >100 movies. I would recommend to wait for an hour before submitting next 100 movies.
