+## Motivation
+
+<div className="motivation">
+  Stripe, Twilio, and AWS have the resources to invest in internal tooling for developer 
+  experience. They provide client libraries in multiple language and developer documentation
+  that stays up-to-date. 
+
+  We are building Fern to productize this process and make it accessible to all
+  software companies.
