+# This script automate the setup of QMI supported wwan devices.
+#
+# Tested on following environment:
+#   * Lenovo ThinkPad X220 (4286-CTO)
+#   * Gentoo/Linux, Linux Kernel 3.9.6
+#   * NTT Docomo UIM card (Xi LTE SIM)
+#   * Sierra Wireless, Inc. Gobi 3000 wireless wan module
+#     (FRU 60Y3257, vendor and device id is 1199:9013)
+#     memo:
+#       I recommend to check if your wwan module works fine
+#       for your mobile broadband provider with Windows
+#       especially if you imported the device from other country.
+#       You may have to initialize your device for your region.
+#   * Required kernel config (other modules may be also required):
+#     - qmi_wwan (CONFIG_USB_NET_QMI_WWAN)
+#     - qcserial (CONFIG_USB_SERIAL_QUALCOMM)
+#   * Required settings:
+#     - you may have to create /etc/qmi-network.conf.
+#       My qmi-network.conf has only a line "APN=mopera.net".
+#
