I'm interested in the DrTechniko workshop on Devoxx4Kids. Can you tell me what programming concept it teaches, what basic supplies are needed for participants, and how someone can contribute new educational materials or translations to Devoxx4Kids workshops in general?
Navigate to the 'Materials' section of the Devoxx4Kids website. From the 'Materials' page, navigate to the 'Workshops' section. On the 'Workshops' page, locate and click the link for the 'DrTechniko Materials Page'. Identify the core programming concept taught in the DrTechniko workshop. List the main tools/supplies required for the DrTechniko workshop. Identify how to contribute new materials or translations to Devoxx4Kids workshops.
State that the DrTechniko workshop teaches programming concepts without a computer, focusing on defining paths. List 'paper and colored pencil' as the main tools/supplies required for the DrTechniko workshop. State that new materials or translations can be contributed via a GitHub pull request.
