Minimal install: add one JSON config script with your assistant context, then load /embed.js.
<script type="application/json" id="chat-widget-config">
{
"chatbot": {
"instructions": "You are the assistant for Zen Slice, an Asian-style pizza shop in Makati City, Philippines. Be friendly, help with menu questions, suggest best sellers, and guide customers to order."
}
}
</script>
<script src="/embed.js"></script>
That is enough to launch. Everything else is optional.
