Understand the default theme
Opening the Theme tab displays the sample theme. This is automatically activated as the default theme, highlighted by the Active icon.
The default theme contains pre-configured settings that can help you start creating your own web store. You can make adjustments to the settings, as required, once you have cloned the theme. You will be able to see those configuration changes in your store/preview after you have activated the newly customized theme.
Details on cloning and configuring your style settings are described in the following sections.
