Contributing translations uses Simpleen, an automated machine learning translation tool, to ensure translations are kept up to date with repository changes. Since our priority is to keep translations up-to-date, any one-time translation contributions will be overwritten by Simpleen in the future.

We do accept glossary changes. Simpleen uses a glossary for key terms that are commonly used across, like trip or station. If you want to suggest a translation for a key term that should be applied across the entire site, you can create an issue on the repository.
