+- [**Integrating Lightning into Bitrefill**][camarena video] - [Justin
+  Camarena][camarena], infrastructure engineer at bitrefill, explains how
+  bitrefill integrated lightning payments into their store. Bitrefill was
+  one of the first Bitcoin merchants to start accepting mainnet Lightning
+  payments, and Justin shows us how they integrated Lightning into their
+  infrastructure, and the challenges they met and overcame along the way.
+  For those interested in a high level overview of bitrefill's experience
+  with Lightning, the [talk by Sergej Kotliar at Building on Bitcoin][kotliar

+  [Jack Mallers][mallers], founder of Zap, explains his approach to product
+  design and user experience. Lightning can potentially solve a lot of user
+  experience issues associated with using Bitcoin, but also brings up some user
+  experience challenges of its own. Jack explains how he thinks about user
+  experience in Zap, the UX challenges he's faced building the product and how
+  he's solved them.
