Why: @lscheske and @nebster believe the origin page from the case for support will increase trust from potential member orgs

Timing: could be (roughly) done in honor of the first anniversary of our founding (3 June 2019)

Text from case for support:

Ben Cerveny, Boris van Hoytema and Arnout Schuijff 
founded the Foundation for Public Code in 2019 to guide international collaboration among public organizations 
around codebase design, quality and governance.

Leveraging 30 combined years of experience working with cities and technology-enabled collaboration, Boris and Ben recognized policy and whitepapers were ineffective catalysts 
in this space. Their landscape analysis revealed that stewardship was the key to converting the massive public investment in open source and collaboration into long-term, sustainable implementation.

Based on their experience of technological innovation in 
a traditional industry, Arnout and Pieter van der Does (co-founders of the Adyen payments platform) agreed 
with Ben and Boris that public organizations deserved 
better software. They joined the Board of Directors to 
share their expertise and connections.
