 ### Development
 
 ```bash
-# Install frontend dependencies (first time only)
-mise run install
-
 # Start both servers (Go API + Vite dev server)
 mise run dev
 # Go API:  http://localhost:8080
 # Vite UI: http://localhost:5173 (with /api proxy)
 ```
 
+**Note**: Dependencies are automatically installed when needed. If you want to manually trigger dependency installation, run `mise deps`.

 `AUTH_TOKEN` defaults to `devtoken` in `mise.toml`. Override it by setting the variable in your environment before running.
 
 Open `http://localhost:5173`, go to **Settings**, enter your token.
