+# larva mk.2
+
+
+
+ Larva keyboard is designed as part of a personal platform for research
+of combined, adaptable, extended latin+cyrillic keymap and layout with better ergonomics for day-to-day use.
+
+ Keyboards, keymap, layouts are developed concurrently, work in symbiosis.
+I name the whole research project "mnemoNИk|Kombine".
+
+ Larva PCB+custom plate fits in "daisy40% hhkb" keyboard case by Kprepublic.
+Larva mk1 has 4 through-hole LED positions, no rgb. Mk2 has in addition 2 rgb smd LED slots for up-facing SK6812MINI-E LEDs
+and 2 pre-assembled mono-color smd LEDs as alternative to 2 lower through-hole LEDs(facedown, was an experimental feature)
+and a few small QoL improvements.
+Current software-side implementation consists of QMK+custom Windows keymap.
+ For activating the bootloader: press the RST button on the back of the pcb.
+
+ (The keyboard design line is constantly evolving, can differ in shapes and sizes, but all serve the same ultimate goal.
+ Current line consists of: Larva mk1; Larva mk2; Katerpillar; Katerpillar Infiltrator; Wodka; Dragonfly; Butterfly; Mothra; Stargate)
+
+
+* Keyboard Maintainer: [grezeh](https://github.com/grezeh)
+* Hardware Supported: *Larva mk.2 pcb (atmega32u4)*
+* Hardware Availability: *discord, occasionally, maybe*
+
+QMK hex file compilation for this keyboard (after setting up your build environment,in QMK SYS for Qmk Toolbox):
+
+ qmk compile -kb grezeh/larva/larva2 -km default
+
+VIAL hex file compilation:
+
+ qmk compile -kb grezeh/larva/larva2 -km vial
+
+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.
