Use the included child theme to keep custom code safe when Lumen updates. Follow the steps below — it takes just a few minutes.

## Before you begin

- Your Envato purchase code (Downloads → License certificate)

## Steps

1. 1Find lumen-child.zipIt is in the full download package, in the Child Theme folder.
2. 2Upload and activate itUpload it like any theme. Lumen must stay installed — the child theme depends on it.
3. 3Copy your settingsLumen → Tools → “Copy settings from parent” brings over colors, menus and widgets.

Tip

Put custom PHP in the child theme’s functions.php, never in Lumen itself.
