+# How to build using vial-qmk
+
+I use vial-qmk instead of qmk-firmware for one reason: The VIA web keyboard configurator does not support Avalanche keyboard yet.
+Web configurator is the gem of QMK based keyboard. VIAL is the one supporting it.
+
+To build:
+``` bash
+git clone https://github.com/peterliu-tw/vial-qmk.git
+cd ./vial-qmk
+qmk compile -kb avalanche/v4 -km vial
+```
+The downside of VIAL-QMK is it use a lot of EEPROM size. In the future:
+# switch back to qmk-firmware when VIA supports Avalanche.
+# Change the microcontroller from ProMicro to RP2040
+
+
+
+# How to flash
+Get QMK Toolbox and google on how to use it.
+
+

+# How to Configure keymap
