+## Lint

+
+## APIs
+
+### Docs
+Go to the url of your project, default [http://localhost:8000](http://localhost:8000) if you didn't disabled the `Docs` route, then you can see docs and try it on.  
+See [demo video](#setup-and-api-usage-demo-video).
+
+### Monitor
+This project got monitor build with swagger-stats, when you got this project running, just go to `<Your Server>:<Your Port>/stats`.  
+For example, [http://localhost:8000/stats](http://localhost:8000/stats)
+
+### Chatbox
+> When you set up the project and didn't disabled the `chatbox` API, you can get a quick-setup chatbot with some basic styles on your own website, which calls the `/v1/chat/completions` API for inference.  
+  
+To set it up, simply add  
 ```html
-<script src='http://localhost:8000/chatbox?base_url=http%3A%2F%2Flocalhost%3A8000' defer></script>
+<script src='http://localhost:8000/chatbox' 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_script = await (await fetch("http://localhost:8000/chatbox")).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.
