Languages
It’s easy to add a new language to your basic Flarum installation. Just follow the instructions below to download and install the language pack of your choice.
Once you have added a language pack, you can set it as the default language for your forum. And if you ever find you don’t need one of your installed language packs, you can always disable it. If you’re using any third-party extensions, be sure to read this before you start.
Language Pack Installation
To begin, visit the Extensions > Languages tag at the Flarum Community site and find a language pack that you want to install.
Language packs are installed the same way as extensions. The language will appear in the Extensions page of the admin interface and you can enable it there.
That’s all there is to it! You should now be able to use the language selector in your site’s header to switch your forum’s display to the new language.
