# Activate your new theme

After you have purchased your _Code Nation_ theme on the [NationBuilder theme store](https://themes.nationbuilder.com/) you can activate it on your site. You'll need to either add it to an existing or new site (we recommend starting with a brand new site, unless you have already started adding content to an unpublished site).

_**Note:**_ _as the manager of the theme marketplace, NationBuilder will issue your new theme, which they commit to delivering within 24 hours of your purchase. As such, you may experience a slight delay between purchasing your theme and being able to apply it to your site._

1 - Find your site in the NationBuilder backend, and click **Theme**. Then navigate to **Switch to a custom theme**, and click the **Switch to** button for the **Code Nation** theme you purchased;
