The concept for the "We Know How" platform originated from a youth group distinguished with the "Origami Crane" award during the 1st Student Hackathon, held as part of the 12th State of the Art Adolescent Health Congress. Co-organized by the MSc "Strategies of Developmental and Adolescent Health", this initiative underscores the active role of young people as agents of knowledge and creativity.

"We Know How" is an innovative digital platform for information and youth engagement, characterized by its "youth-to-youth" approach—the creation and dissemination of content by youth, for youth. This methodology aligns directly with the core principles of Developmental and Adolescent Health.

Through the website https://we-knowhow.gr/, the platform:

• Provides evidence-based and youth-friendly information for children, adolescents, and young adults.
• Encourages the expression of thoughts, experiences, and concerns.
• Cultivates digital literacy and psychosocial skills through thematic areas such as health, mental well-being, nutrition, society, environment, and creative expression.

During the COVID-19 pandemic, the platform functioned as a secure space for communication and creative participation. Supported by scientific collaborators, it serves as a hallmark example of a contemporary digital intervention that is intrinsically linked to the philosophy and objectives of the MSc.
