+# Planck Through Hole Kit
+
+![THK](https://i.imgur.com/Fj8X0TDl.jpg)
+
+The OG 4x12, through-hole, ortho board.
+
+[Buildlog](https://erovia.github.io/posts/thk/)
+
+* Keyboard Maintainer: [Erovia](https://github.com/Erovia)
+* Hardware Supported: [Planck THK](https://github.com/olkb/planck_thk)
+* Hardware Availability: The hardware was released under GPLv3, see link above.
+
+Make example for this keyboard (after setting up your build environment):
+
+    make planck/thk:thk
+
+Flashing example for this keyboard:
+
+    make planck/thk:thk:flash
+
+**Reset**: With [the recommended bootloader](https://github.com/Erovia/planck_thk_usbasploader) a single press on the RESET button.
+
+## Audio
+
+The board has rudimental [audio](https://docs.qmk.fm/#/feature_audio) support.  
+As it can cause the USB connection to crash, likely due the mcu not being able to keep up with the USB's strict timing requirements, it's is disabled for the `thk` keymap.
+
+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).
