The core plugin and each add-on ships with a standard POT file. The file can then be used by many popular translation tools to create your own .PO and .MO files that render the text in the language of your choice.
The core plugin has been translated into a number of languages by volunteers. Most popular languages have had 100% of the strings translated. The add-ons, however, do not have as many languages readily available but you can translate them using the included .POT files at any time.
If you would like contribute to the translation effort, you can join the projects on www.poeditor.com. By performing your translations on this site you can share your language skills with other users and, in turn, they will share their language skills with you!
The first step is to access the translations project page and register a new account on www.poeditor.com. Then, you should contact us to have us add a slot for the language you need – contact us using our contact page or by opening a support ticket.
Once we have approved your account and added your language you can proceed to translate the strings.
