+The following Yunsilicon device models are supported by the same xsc driver:
+
+  - metaScale-200S
+  - metaScale-200
+  - metaScale-100Q
+  - metaScale-50
+
+Prerequisites
+--------------
+
+- Follow the DPDK :doc:`../linux_gsg/index` to setup the basic DPDK environment.
+
+- Learning about Yunsilicon metaScale Series NICs using
