+## Embed your chatbot into website
+To embed a chatbot to your website, simply add  
+```html
+<script src='http://localhost:8000/chatbox?base_url=http%3A%2F%2Flocalhost%3A8000' defer></script>
+```
+into the bottom of your html body element. So easy!  
+Please change the `http://localhost:8000` and the base_url in request query to your real host to make sure it works.  
+
+If you want to hide the real link, in your javascript code you can do  
+```js
+const chatbox_script = await (await fetch("http://localhost:8000/chatbox?base_url=http%3A%2F%2Flocalhost%3A8000")).blob();
+const chatbox_url = URL.createObjectURL(chatbox_script);
+const script_elem = document.createElement('script');
+script_elem.src = chatbox_url;
+document.body.append(script_elem);
+```
+And remember to use `URL.revokeObjectURL(chatbox_url)` if you don't need it anymore.
