+# NIBBLE
+
+![NIBBLE](https://nullbits.co/static/img/nibble1.jpg)
+
+A unique, tweakable 65% keyboard kit built by nullbits. [More info at nullbits.co](https://nullbits.co/nibble/)
+
+* Keyboard Maintainer: [Jay Greco](https://github.com/jaygreco)
+* Hardware Supported: NIBBLE Rev1, Pro Micro comaptible MCUs.
+* Hardware Availability: [nullbits.co](https://nullbits.co/)
+
+Note: If you are seeing issues with MacOS and keyboard hangs after sleep, make sure `NO_USB_STARTUP_CHECK = yes` is set in your rules.mk.
+
+Adds experimental "Remote Keyboard" functionality, which forwards keystrokes from an external macropad, keyboard, or numpad over UART/TRRS, removing the need for an additional USB connection. 
+
+Make example for this keyboard (after setting up your build environment):
+
+    make nullbitsco/nibble:default
+
+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).

+Remote keyboard is an experimental feature that allows for connecting another
+keyboard, macropad, numpad, or accessory without requiring an additional USB connection.
+The "remote keyboard" forwards its keystrokes using UART serial over TRRS. Dynamic VUSB 
+detect allows the keyboard automatically switch to host or remote mode depending on
+which is connected to the USB port.
+
+Possible functionality includes the ability to send data from the host to the remote using
+a reverse link, allowing for LED sync, configuration, and more data sharing between devices.
+This will require a new communication protocol, as the current one is limited.
