+![SAM SG81M](https://i.imgur.com/x0Cj807.jpg)
+
+* Keyboard Maintainer: [CMM.Studio Freather](https://github.com/CMMS-Freather)
+* Hardware Supported: PCB, Atmega32u4
+
+Make example for this keyboard (after setting up your build environment):
+
+    make sam/sg81m:default
+
+
+For reset instruction, use tweezer to short the reset pin and ground pin to enter bootloader mode
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
