+
+## Support
+Keyboard Maintainer: [Matthew Kerfoot(https://github.com/mkerfoot)  
+Hardware Supported: ATOM47  
+Hardware Availability: [GeekHack.com Group Buy](https://geekhack.org/index.php?topic=93447.msg2545221)  
+
+
+## Features
+QMK Firmware
+6 Underglow RGB leds
+In-switch leds
+Through-hole micro usb connector (less likely to break off!)
+South facing leds for the QMX/Zealencio users
+Multiple layouts
+Easily reachable reset button under the spacebar
+CapsLock indicator
+
+## Build
+To build the default keymap, simply run `make atom47:default`.
+
+For an alternative, heavily modified layout you would just need to run `make atom47:LEdiodes`.
+
+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.

+ * Descriptor handling is configured through the descriptor's properties. If
+ * no properties are defined or if they are 0, the default descriptor is used.
+ * Possible properties are:
+ *   + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
+ *     at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
+ *     used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
+ *     you want RAM pointers.
+ *   + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
+ *     in static memory is in RAM, not in flash memory.
+ *   + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
+ *     the driver must know the descriptor's length. The descriptor itself is
+ *     found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):
+ *   char usbDescriptorDevice[];
+ *   char usbDescriptorConfiguration[];
+ *   char usbDescriptorHidReport[];
+ *   char usbDescriptorString0[];
+ *   int usbDescriptorStringVendor[];
+ *   int usbDescriptorStringDevice[];
+ *   int usbDescriptorStringSerialNumber[];
+ * Other descriptors can't be provided statically, they must be provided
+ * dynamically at runtime.
+ *
+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
+ *
+ * The following descriptors are defined:

+ *   USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
+ *
+ * Note about string descriptors: String descriptors are not just strings, they
+ * are Unicode strings prefixed with a 2 byte header. Example:
+ * int  serialNumberDescriptor[] = {
+ *     USB_STRING_DESCRIPTOR_HEADER(6),
