+OpenBMC Evaluation Board (EVB)
+================
+
+This is the OpenBMC Evaluation Board (EVB) layer. The boards in the EVB layer
+are for evaluation and reference. The [Board Support Package (BSP)
+layer](https://github.com/openbmc/openbmc/tree/master/meta-openbmc-bsp)
+should be used to support a hardware device in a system. Therefore, there
+should not be any EVB layers in a system's bblayers.conf, the BSP layer should
+be used instead. Boards might be found be in both the EVB layer and the BSP
+layer.
