+# Avalanche
+
+![Avalanche v3.0](https://github.com/vlkv/avalanche/blob/master/images/avalanche_v3-0.jpg)
+
+An open source ergonomic split keyboard with removable keys to support 40% and 60% configurations.
+
+* Keyboard Maintainer: [Vitaly Volkov](https://github.com/vlkv)
+* Hardware Supported: Avalanche PCB v1, v2, v3, Pro Micro 5V/16MHz and compatible.
+* Hardware Availability: [Avalanche](https://github.com/vlkv/avalanche).
+
+Make example for this keyboard (after setting up your build environment):
+
+    make avalanche/v1:default  # for v1 PCBs
+    make avalanche/v2:default  # for v2 PCBs
+    make avalanche/v3:default  # for v3 PCBs
+
+Flashing example for this keyboard:
+
+    make avalanche/v1:default:flash  # for v1 PCBs
+    make avalanche/v2:default:flash  # for v2 PCBs
+    make avalanche/v3:default:flash  # for v3 PCBs
+
+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
+
+Briefly press the button along the inner edge of the PCB next to the microcontroller.
