+Port the default Atreus layout to the Levinson/Let's Split.
+
+The purpose is to try out the layout to get a sense of what works in it.
+
+The 'extra' keys on the Levinson are dead in this version, to make a
+more faithful emulation of the atreus layout.

+# jyh's levinson layout
+
+[Levinson](https://keeb.io/products/levinson-lets-split-w-led-backlight)
+built on rev2 PCBs. A split 4x12 keyboard with LED backlights.
+
+The layout is oriented towards needs for programming, Emacs, XMonad,
+and experience with 60% keyboards with no base layer arrow keys
+(Poker). It makes heavy use of modifiers and layers.
+
+## Layout features
+
+  * Extensive use of _Mod Tap_, e.g.
+     * Tap sends Esc, Hold sends Left Control
+     * Tap sends Enter, Hold sends Right Shift
+     * ... and many more
+  * Hyper and Meh keys
+  * Right modifier keys in place of arrow keys
+    * Arrows are instead available in two alternate locations:
+    * WASD arrows on _Adjust_
+    * Arrow cluster on _Raise_ (inspired by hexwire)
+  * Centered symbol/bracket cluster on _Lower/Raise_
+    * Inspired by hexwire layout
+    * Programming-oriented
+  * Spacebar sends modifier keys on hold (_this is finicky in practice. may shut off completely_)
+    * Control ~~and Alt/Meta~~ on left ~~and right~~ space, respectively
+    * Strict space available on _Function_ and _Numpad_ layers
+    * For Emacs keychords
+  * Extra dedicated layers
+    * Numpad (available with tap toggle)
+    * Function key (F01-24)
+  * Redunant keys where it is convenient to have characters together
+    on one layer

+
+[Levinson](https://keeb.io/products/levinson-lets-split-w-led-backlight)
+built on rev2 PCBs. A split 4x12 keyboard with LED backlights.
+
+The layout is oriented towards needs for programming, Emacs, XMonad,
+and experience with 60% keyboards with no base layer arrow keys
+(Poker). It makes heavy use of modifiers and layers. It is influenced
+by good ideas from the Atreus keyboard layout.
+
+## Layout features
+
+  * Extensive use of _Mod Tap_, e.g.
+     * Tap sends Esc, Hold sends Left Control
+     * Tap sends Tab, Hold activates Numpad layer
+     * Tap sends  - , Hold sends Shift
+     * ... and many more
+  * Places Tab and Enter on bottom corners, for hitting with palm
+  * Meta is available on top corners, for controlling XMonad
+  * Control on center key, for Emacs (among other things)
+  * Backspace (Control Hold) and Space on center keys
+  * All 60% keys available on base layer, except for numbers
+  * Hyper and Meh keys
+  * Right modifier keys in place of arrow keys
+    * Arrows are instead available in two alternate locations:
+    * WASD arrows on _Adjust_
+    * Arrow cluster on _Raise_ (inspired by hexwire)
+  * Numpad and Numrow on _Raise_ layer. Each is faster in some contexts
+  * Function keys on _Lower_
+  * Dynamic macros from QMK firmware on _Adjust_
+  * Redunant keys where it is convenient to have characters together
+    on one layer

+Vinta
+=========
+
+[Vinta](https://i.imgur.com/huX3lff.jpg)
+
+
+This is an ARM-powered 65% keyboard PCB with USB Mini B connector and breakout for optional RGB underglow.
+
+Keyboard Maintainer: [Peioris](http://peioris.space/) and on [github](https://github.com/coarse)  
+Hardware Supported: Vinta with STM32F042K6T6  
+Hardware Availability: Private Groupbuy (will post on Reddit once QMK has RGB underglow working)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make vinta:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
+
+#### Developer's Note
+
+STM32F042xx chips does not allow jumping to bootloader without BOOT0 being set to high, therefore it is impossible to enter the bootloader from sending a `RESET` keycode nor using bootmagic or bootmagic lite.  
+The only way to enter bootloader is to hold the BOOT0 button while the keyboard is powering up or after a power reset (done by pressing the reset switch or sending a `RESET` keycode).
