+## Meshpacket
+
+To support functionality of Store and Forward, a new enum has been added to the MeshPacket.
+
+```
+typedef enum _MeshPacket_Delayed {
+    MeshPacket_Delayed_NO_DELAY = 0,
+    MeshPacket_Delayed_DELAYED_BROADCAST = 1,
+    MeshPacket_Delayed_DELAYED_DIRECT = 2
+} MeshPacket_Delayed;
+```
+
+* NO_DELAY - The packet was set in real time. Store and Forward had no hand in this message. This is the default case.
+* DELAYED_BROADCAST - This is a delayed message. The 'to' of the packet has been directed at a named user but was previously a broadcast packet.
+* DELAYED_DIRECT - This is a delayed message. The 'to' of the packet has been directed at a named user but was previously a direct packet.
+
+As a reminder, broadcast messages are messages where the "to" of a payload is directed at NODENUM_BROADCAST or (0xFFFFFFFF).
+
+Example Cases:
+
+* Real time :: BROADCAST
+* * Delayed = MeshPacket_Delayed_NO_DELAY
+* * From: Ann
+* * To: BROADCAST
+* Real time :: Direct
+* * Delayed = MeshPacket_Delayed_NO_DELAY
+* * From: Ann
+* * To: Bob
+* Delayed :: BROADCAST
+* * Delayed = MeshPacket_Delayed_DELAYED_BROADCAST
+* * From: Ann
+* * To: Bob
+* Delayed :: Direct
+* * Delayed = MeshPacket_Delayed_DELAYED_DIRECT
+* * From: Ann
