After you have purchased your Code Nation theme on the NationBuilder theme store 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existing or new site (we recommend starting with a brand new site, unless you have already started adding content to an unpublished site).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;
2 - Finally, select whichever colour style best suits your campaign.
