Key Decisions

To start, I defined the key design aspects that would turn this project into a success. Frictionless interaction, clear communication, and in-context educational content were the principles we adopted in order to provide new users with a trustworthy, easy-to-use onboarding.
The design system benefited from new components and styles while the partnership with the content team helped us introduce new illustrations and animations to give this flow it's flavour.
