Translations:LibreOffice Localization Guide/8/en
Localizing LibreOffice is not a small task, and it has many levels. The lowest one is to assure that LibreOffice handles your script (if it is not Latin-based) correctly. LibreOffice should allow people in your country to work using your script, even if its interface is in English or other foreign language. Checking for support for your script might be a task that you can do by yourself, but translating whole LibreOffice interface to a new language is task much larger, requiring over one man/year, so ideally, several people should be involved.
