 | `OPEN_TERMINAL_PIP_PACKAGES` | Space-separated list of **pip** packages to install at startup |
+| `OPEN_TERMINAL_NPM_PACKAGES` | Space-separated list of **npm** packages to install globally at startup |
 
 > [!NOTE]
 > Packages are installed each time the container starts, so startup will take longer with large package lists. For heavy customization, build a custom image instead.
