+#
+# Allow flashing pic32 boards using:
+#  * Microchip PICkit2
+#  * Microchip PICkit3 with script firmware
+#
+#
+# PICkit-3
+# --------
+#
+# This requires changing the firmware to 'scripting mode'
+# Should be done from a Windows computer/virtual machine as described here
+#
+# https://github.com/RIOT-OS/RIOT/blob/master/dist/tools/pic32prog/doc.md
+#
+#
+# Udev rule
+# ---------
+#
+# Add yourself to the `plugdev` group, add the following `udev` rule to
+# `/etc/udev/rules.d/26-microchip.rules` and reboot.
+#
+# ```
+# # Adapted from http://en.microstickplus.com/mplabx-on-linux
+# ATTR{idVendor}=="04d8", MODE="664", GROUP="plugdev"
