+# alix40
+
+
+
+Minimal hacker style mechanical keyboard designed in Tokyo. Cherry MX compatible. More Info at [Tokyo Keyboard](http://tokyokeyboard.com).
+
+* Keyboard Maintainer: [quadcube](https://github.com/quadcube)
+* Hardware Supported: alix40 rev1
+* Hardware Availability: [Tokyo Keyboard](http://tokyokeyboard.com)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make tokyokeyboard/alix40:default
+
+See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
+
+Note:
+1. Be very careful and gentle when disassembling the PCB from the bottom case
+2. alix40 battery power switch (shown in the image below) is used to toggle battery usage (on: battery will be charged when USB is connected, keyboard will be on when USB is disconnected/off:battery will not be charged when USB is connected, keyboard will be off when USB is disconnected)
+
+3. Install the slider on the battery power switch (bundled together with the 3M feets)
+4. Underglow RGBs are switched off when alix40 is running on battery power (hardware feature to extend battery usage time)
