+## Our Commitments
+
+We believe in open source and we act on that belief. We became Silver Members 
+of the Linux Foundation because we wanted to formally support the ecosystem 
+we build on every day. Open standards, open collaboration, and open governance 
+are part of how we work and how we think about software.
