+# To update this file, create a new file
+# /etc/udev/hwdb.d/70-keyboad.hwdb
+# and add your rules there. To load the new rules execute (as root):
+# udevadm hwdb --update
+# udevadm trigger /dev/input/eventXX
+# where /dev/input/eventXX is the keyboard in question. If in
+# doubt, simply use /dev/input/event* to reload all input rules.
+#
+# If your changes are generally applicable, open a bug report on
+# http://bugs.freedesktop.org/enter_bug.cgi?product=systemd
+# and include your new rules, a description of the device, and the
+# output of
+# udevadm info /dev/input/eventXX
+# (or /dev/input/event*).
