# TORN// Split Through Hole
![torn](https://raw.githubusercontent.com/rtitmuss/torn/master/doc/img/torn.jpg)
The split keyboard kit made by through hole components only.
The design has been inspired by the Corne, Plaid and Discipline keyboards.
* Keyboard Maintainer: [rtitmuss](https://github.com/rtitmuss)
* Hardware Supported: TORN, atmega328p
* Hardware Availability: [GitHub](https://github.com/rtitmuss/torn)
Make example for this keyboard (after setting up your build environment):
make torn:default
Flashing example for this keyboard:
make torn:default:flash
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).
