- Download Poedit to your PC.
- Before translating, please make sure to click on the "Update" button in Poedit, so you have the latest string of the add-on.
- Translate the file which is located in "plug-in name"/static/language folder.
- Name the translated file accordingly: wp-invoice-pdf-dk_DK.po (if this is for wp-invoice-pdf for dutch translation). Make sure that the abbreviations are correct.
