+## Custom Node.js Mirror
+
+By default, Vite+ downloads Node.js from `https://nodejs.org/dist`. If you're behind a corporate proxy or need to use an internal mirror (e.g., Artifactory), set the `VP_NODE_DIST_MIRROR` environment variable:
+
+```bash
+# Install a specific version from your custom mirror
+VP_NODE_DIST_MIRROR=https://my-mirror.example.com/nodejs/dist vp env install 22
+
+# Set the global default version using a custom mirror
+VP_NODE_DIST_MIRROR=https://my-mirror.example.com/nodejs/dist vp env default lts
+
+# Set it permanently in your shell profile (.bashrc, .zshrc, etc.)
+echo 'export VP_NODE_DIST_MIRROR=https://my-mirror.example.com/nodejs/dist' >> ~/.zshrc
+```

-The distribution URL can be overridden using the `VITE_NODE_DIST_MIRROR` environment variable. This is useful for corporate environments or regions where nodejs.org might be slow or blocked.
