+![Default Layout](https://github.com/walterhanley/wren-keyboard/blob/main/images/author-layout.png?raw=true)
+
+# Default Wren Layout
+
+This is the default Wren layout, which lacks any layers. It should be fairly 
+straightforward, with the sole exception of the equals key in the place of the 
+grave key and the grave key in the place of the delete key. 
+
+This layout preserves the entire keyboard matrix, but only includes keycodes 
+for a numpad/nav cluster configuration. Depending on your configuration, you 
+may need to replace some of the existing KC_NO values with actual keycodes.

The storm that wipes out the pathetic little thing you call your life. You're fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that's just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little 'clever' comment was about to bring down upon you, maybe you would have held your fucking tongue. But you couldn't, you didn't, and now you're paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it. You're fucking dead, kiddo.");

+# Author's Wren Layout
+
+This is my personal Wren layout, which includes a few layers and macros that 
+I find useful. It started as a clone of the default keymap, but will likely
+diverge more as time goes on.
+
+Please note that this layout preserves the entire keyboard matrix, but only 
+includes keycodes for a numpad/nav cluster configuration. Depending on your 
+configuration, you may need to replace some of the existing KC_NO values 
+with actual keycodes.

+![Wren Layout](https://raw.githubusercontent.com/walterhanley/wren-keyboard/main/images/author-layout.png)
+
+A split ergonomic "system keyboard" aimed at providing numpad and nav cluster functionality. For more information, please see the [project repo](https://github.com/walterhanley/wren-keyboard).
+
+* Keyboard Maintainer: [Walter Hanley](https://github.com/walterhanley)
+* Hardware Supported: Wren Universal PCB and Elite C (Pro Micro configurations likely supported but not tested)
+* Hardware Availability: Source files available at [project repository](https://github.com/walterhanley/wren-keyboard)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make wren:default
+
+Flashing example for this keyboard:
+
+    make wren: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 2 ways:
+
+* **Physical reset button**: Briefly press the button on the front of the PCB below the microcontroler
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
