+# Mode SixtyFive M65S
+
+![MODE75](https://raw.githubusercontent.com/Gondolindrim/file_hosting/main/mode_sixtyfive/Group_95_1024x1024.jpg)
+
+The M65S is the solderable PCB for the Mode SixtyFive keyboard, a sixty-five-percent high-end keyboard sold by [Mode Designs](https://shop.modedesigns.com/).
+
+-   Keyboard Maintainer: [Gondolindrim](https://github.com/Gondolindrim)
+-   Hardware Supported: proprietary PCB using STM32F401 controller
+-   Hardware Availability: you can get a Mode SeventyFive via when preorders open in 2022 [Mode Designs](https://shop.modedesigns.com/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make mode/m65s:default
+
+Flashing example for this keyboard:
+
+    make mode/m65s:default:flash
+
+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).
