 ## Advanced Settings 🛠
 
-### For those who want to use `Official ChatGPT(GPT3.5-turbo)` or `GPT-3`
+By default, `AiShell` is configured to use the reverse-engineered ChatGPT client and retrieve login information from your browser, so you don't need to configure anything to use `AiShell`. However, for those who want to use different models with an OpenAI API Key, you can configure it as follows:
+
+1. Create an account on OpenAI.
+1. Go to <https://platform.openai.com/account/api-keys> and copy your API key.
+1. Modify or create the `~/.aishell/config.json` file as follows:
 
-1. Create account on OpenAI
-1. Go to <https://platform.openai.com/account/api-keys>, Copy API key
-1. Modify or create `~/.aishell/config.json` file like following
+  ```json
+  {
+      ...
+      "language_model": <language model of your preference>, //"official_chatgpt" or "gpt3"
+      "openai_api_key": <your OpenAI API key>
+  }
+  ```
 
-    ```sh
-    {
-        ...
-        "language_model": <language model of your preference>, //"official_chatgpt" or "gpt3"
-        "openai_api_key": <your openai api key>
-    }
-    ```
+Here, you can specify the language model of your preference, such as "official_chatgpt" or "gpt3", and add your OpenAI API key. This will enable AiShell to use the specified language model and API key when executing commands.
