Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
I am a native speaker and living in Germany. That's why I created a language file.

Additional context
yml is in the zip file. Maybe you want to add it to your repository.
lang-DE.zip

Thanks for your work! I'd be happy to add it to AntiWorldFly, would you like to create a pull request with the new lang file so you get credit for it on GitHub?

You could also set the commit's author to their no-reply GitHub mail address, they will get credit without having to submit a pull request. 😉
