+Step 1~4 show how to build and execute NPS kernel modules.
+
+1. Modify nps-modules/config.mk to specify the output directory to BUILD_OUTPUT_DIR.
+   The default output path is nps-modules/build.
+
+2. Compile:
+   cd nps-modules/ && make
+
+3. The output kernel modules will be found in $(BUILD_OUTPUT_DIR)/modules/
+   - nps_dev.ko
+   - nps_netif.ko
+
+4. Load modules:
+   (1) insmod nps_dev.ko
+   (2) insmod nps_netif.ko
+
+   Note that the module inserting sequence cannot be changed.
