To create a new theme, navigate to your menu and click on "Themes".
Clicking the "New Theme" button will open a widget displaying your brand colors and fonts, making it easy to create an on-brand theme, every time.
Confirm by hitting the "Lookin' good" button, which will take you to the Theme Editor.
Three important steps are highlighted on the image above:
1. Start by giving your theme a suitable name.
2. If you like, you can set this as your default theme.
3. Save your changes, and hit "Back" to view all of your custom themes.
You can also edit the custom copy fields in the Theme Editor — find out how here.
