 ## How to Use
 
-### 1. Using After CLI Proxy API Program Launch (Recommended)
-Once the CLI Proxy API program is up and running, you can access the WebUI at `http://your-server-IP:8317/management.html`.
+1) **After CLI Proxy API is running (recommended)**  
+   Visit `http://your-server:8317/management.html`.
 
-### 2. Direct Use
-Simply open the `index.html` file directly in your browser to use it.
+2) **Direct static use after build**  
+   The single file `dist/index.html` generated by `npm run build`
 
-### 3. Use a Local Server
-
-#### Option A: Using Node.js (npm)
+3) **Local server**
 ```bash
-# Install dependencies
 npm install
-
-# Start the server on the default port (3000)
-npm start
-```
-
-#### Option B: Using Python
-```bash
-# Python 3.x
+npm start        # http://localhost:3000
+npm run dev      # optional dev port: 3090
+# or
 python -m http.server 8000
-
 ```
+   Then open the corresponding localhost URL.
 
-Then open `http://localhost:8000` in your browser.
+4) **Configure connection**  
+   The login page shows the detected address; you can override it, enter the management key, and click Connect. Saved credentials use encrypted local storage for auto-login.
 
-### 3. Configure Connection
-1. Open the management interface.
-2. On the login screen, enter:
-   - **Remote Address**: The current version automatically picks up the remote address from where you're connecting. But you can also set your own address if you prefer.
-   - **Management Key**: Your management key
-3. Click the "Connect" button.
-4. Once connected successfully, all features will be available.
