To use templates in Botpress, first visit the Botpress Hub at https://botpress.com/hub?type=Template and click on the template you'd like to add to your workspace. Download the template to your Desktop. Then, go into the Botpress Studio, create a new bot, and choose 'Start from Scratch'. Once your bot is created, click on the Botpress logo on the left-hand side, then select 'Import/Export'. Finally, drag the downloaded template from your Desktop to import it into your bot.
