The plugin comes with .po file included under the languages folder. To translate:

1. Download and install Poedit.
2. Open bookmify.po to file located here \wp-content\plugins\bookmify\languages\ using the poedit tool and translate the existing text to your own
3. Save the file with the locale (for example ru_RU.po).
4. A step above should have generated a .po and a .mo file. Copy both these files and put them into the languages folder of the theme.

Your Language & Localization

After translating, you may wish to use the correct locale to translate and localize your WordPress installation completely. Refer to Installing WordPress In Your Language at WordPress Codex to learn how to.
