The "language" block is a powerful feature of the translate extension. You can use it to make a project that is automatically translated into the language of whoever is viewing it! This tutorial shows how (and how it works with text to speech, too). Bonus: this tutorial uses the same technique to translate itself, so the text at the top should show up in your language (if you want to test that out, you can temporarily change your own language setting at the bottom of this page, or in the editor)
