+# NOAH 65 keyboard
+
+![NOAH](https://raw.githubusercontent.com/yulei/qmk_webusb_tool/master/public/noah.jpg)
+This was the first 65% keyboard made by the Matrix team, it had the following features:
+
+- per key rgb led
+- 7 RGB led for caps, scroll , num lock and layer state indicator, or just play light animation effects
+- ansi and iso layouts, and split spacebar supported
+- pre-programmed bootloader which emulated usb stick to ease firmware updating
+
+Keyboard Maintainer: [astro](https://github.com/yulei)  
+Hardware Supported: Matrix NOAH keyboard
+Hardware Availability: [NOAH Keybaord](https://geekhack.org/index.php?topic=102300.0)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make matrix/noah: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).
