+# Mesh Internal Communication Example
+
+This example demonstrates how to use the mesh APIs to set up a mesh network, send and receive messages over the mesh network and etc.
+
+Features Demonstrated
+
+- mesh initialization
+
+- mesh configuration
+
+- mesh start
+
+- mesh event handler
+
+- root send and receive
+
+- other nodes receive
+
+Open project configuration menu (`idf.py menuconfig`) to configure the mesh network channel, router SSID, router password and mesh softAP settings.
+
+When the mesh network is established and if you happen to run this example on ESP-WROVER-KIT boards, the RGB light indicator will show you on which layer devices are.
+The pink reprents root; the yellow reprents layer 2; the red reprents layer 3; the blue reprents layer 4; the green reprents layer 5; the white reprents layer greater than 5.
+Root continuously sends an On / Off control message to all devices in its routing table. Devices including root itself receive this message and do the On / Off.
