+# 0x3E
+
+An 60%-ish Ortholinear Low-profile (Kailh Choc) Keyboard, with Boardwalk-like layout (1.5u outer mod colums, split spacebar) and OLED display
+
+* Keyboard Maintainer: [plut0nium](https://github.com/plut0nium)
+* Hardware Supported: 0x3E PCB
+* Hardware Availability: [MKUltra](https://mkultra.click)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make plut0nium/0x3e: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).

+## How to reset the board into bootloader mode
+
+The PCB has a dedicated Reset pushbutton on the underside, press it once to reset the board into bootloader mode.
+In addition, bootmagic lite is enabled in the default config, holding ESC (upper left key) while plugging the board will start in bootloader.
