Read Open Letter to the Gatsby Open Source Community by Kyle MathewsKyle Mathews (Gatsby)
Gatsby is a React-based open source framework with performance, scalability and security built-in. Collaborate, build and deploy 1000x faster with Gatsby Cloud.

Chris has written a bit about his process as well: Building Gatsby Plugin Webmentions.
