* What’s worked well (or poorly) for encouraging contributions and getting users to help improve the docs?
If you have time to browse the current docs \[1], I’d love to hear what’s missing, what’s confusing, or what stands out as helpful.
I’m here to learn from your experience—tools, workflows, hosting decisions, contributor strategies, anything. Thanks in advance!

Localization is challenging because it requires synchronisation between the product and developer teams. Many solutions exist to provide online localisation services supporting various input formats such as GNU gettext and ResX files. But a strong requirement, the code should not leave the company’s premises, removed almost all available solutions. Not to mention that they were also quite expensive. Weblate on the other hand combines the advantages of being free and self-hosted. The code would not have to leave the premises, and support is affordable.
