Crowdsourced translation (i18n/l10n)
Exploring your mod, i can see that it's missing a french translation. I've helped localize several projects in french since 2023 and would be happy to help with this one as well :) It understand the usual process requires you download specific files and edit them on your end, knowing what to do and how to do it, then send them through git. This solution works for those who are already familiar with git and coding in general, which is unfortunately not the case for many potential translators.
This is why i kindly ask that you allow translating the Goblins mod through an external crowdsourcing tool.
If you so choose, i'd recommend you allow it through a hosted translation tool like Weblate (which is FOSS and provides free hosting for FOSS projects), because it's crowdsourced and helps a lot with people like me who are not used to coding and using Git
Finally, if you decide upon one of these solutions, be sure to promote the localization of this mod in public facing communication (the readme file for example), so that users who want to can easily contribute :)
