Translations:LibreOffice Localization Guide/7/en
Check out the list of LibreOffice language teams to make sure that there is not already a localization project for your language. If there is one, write to the person that appears as project contact, to know the status of the project and see if it is makes sense to participate in it. Bear in mind though that sadly, not all teams have taken time to list themselves in that page, so a missing table row doesn't necessarily mean that there is no team. You are also advised to check out other pages in Category:L10n and take a quick look at Weblate, and if the status of your locale is still unclear, probably contact the L10n mailing list.
