+## SDK Iterations
+
+
+### Protocol messages
+
+[New protocol spec](https://docs.google.com/document/d/1Qh2h07T_qepzEJ7IytmxwIdQAOsGHrvhXwZxuZtbwgc/edit#) clearly defines all message types with examples. It's based on [transit-format](https://github.com/cognitect/transit-format), so it makes sense to evaluate its [go implementation](https://github.com/russolsen/transit)
+
+Use cases:
+
+### General
+#### [ ] Message
+
+##### Parameters:
+  - content: the content of the message (a map or a string for now)
+  - content-type: the content-type of the message
+  - message-type: the type of the message
+  - to-clock-value : the clock of the sender for message ordering
+  - timestamp: the timestamp of message
+
+*Where does the destination/s of the message is defined?*
+
+
+#### Private groups
+
+##### [ ] NewGroupKey
+
+- [ ] GroupAdminUpdate
+- [ ] GroupLeave
+
+#### Contact management
+- [ ] NewContactKey
+- [ ] ContactRequest
+- [ ] ContactRequestConfirmed
+- [ ] ContactUpdate
+
+#### Not needed for first iteration
+- [ ] Seen
+
+
+##### Message
+
+
+### Define final SDK UI based on different messages
