+Setting up udev rules
+=====================
+
+For convenience, you may install udev rules file, 10-stlink.rules, located
+in the root of repository. You will need to copy it to /etc/udev/rules.d,
+and then either reboot or execute
+$ udevadm control --reload-rules
+
+Udev will now create a /dev/stlink file, which will point at appropriate
+/dev/sgX device. Good to not accidentally start debugging your flash drive.
