Hi Ertuğrul,

Yes you are right. You need to create po and mo file using poedit to translate in your own language. You can make a copy of interface.pot file ( if you like to change language in russian then rename it interface copy.pot to ru_RU.po) Open ru_RU.po file using poedit. Then you can edit it. Your mo file will be automatically generated.

Hope this may help you
Thank you!
