I want to hire at least 2 translators to do this work at the same time.
Requirements:
1. No machine/auto- translation. English to Russian translation.
2. Write the translation just under each English paragraph in the same file. Don't change the name of the file.
3. Pay attention to the technical words of icon/menu/button in the program. You can check the pictures I attached to learn the corresponding translation of icon/menu/button in the program.
4. Wondershare PDFelement is our product's name, just leave as it is.
