Translation platform
It would be great if there was a convenient way for general public to contribute translations.
I can recommend Weblate, as it's popular, the platform itself is open source (compared to others), can be self hostable, and for open source projects like yours, they host translations for free. Weblate automatically merges translations and if you want you can have different widgets shown in github readme, that displays how much percentage each applied language is translated to in real-time. It's much more simple for people to translate this way and it's free + less work needed for you.

@zbejas Turn off using the main component as a dictionary at the bottom of https://hosted.weblate.org/settings/portarius/application/ (makes translation harder, since now it is a question of navigating a dictionary.) I can help if you add "kingu" in https://hosted.weblate.org/access/portarius/#users :)
