+# Nyquist LM
+
+A low-profile 60% split 5x12 ortholinear keyboard made and sold by Keebio. [More info at Keebio](https://keeb.io).
+
+* Keyboard Maintainer: [Bakingpy/nooges](https://github.com/nooges)
+* Hardware Availability: [Keebio](https://keeb.io/)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make keebio/nyquist_lm/rev1:default
+
+Example of flashing this keyboard:
+
+ make keebio/nyquist_lm/rev1: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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the key at the top left of left half or top right of right half and plug in the keyboard
+* **Physical reset button**: Press and hold the button on the back of the PCB for at least 1 second and let go
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
