Themes are the design.efficiently version of a client presentation template. You have the option to create your own theme(s), or use the design.efficiently themes which can be customized to your liking.
Any user can access the default Minimalist Theme, as well as a blank Theme from within any project, immediately upon signing up. In order to access other design.efficiently themes or any custom themes you create with your branding, the administrator will have to add these themes into their org for use by other users.
To add Themes to your Org, follow the steps below:
Step 1: Navigate to the Admin Console, and select the Book Themes tab.
Step 2: The themes listed on the left hand side (the default Minimalist Theme and a blank Untitled Theme) are automatically set as the default options for all users from within any project (they can easily be removed once you've added your own preferred themes). To add another theme to your list of options, click the blue '+'.
Step 3: Select the theme you wish to add to your org from the list on the left and click Select Theme in the bottom right corner.
Step 4: Name the new Theme and click Create.
Step 5: Your new Theme will now be available to all users in your org at the project level. Click < Themes to return to your full list of available themes.
Note: To create your own theme, select the blank Untitled Theme and edit to your liking. You can add additional blank templates by selecting the blue '+' button.
Step 6: Select the star next to the theme you wish to set as your org's default theme. This is the theme that will automatically surface first whenever a user clicks to create a book.
