+# Acheron Themis QMK firmware
+
+
+
+The Themis is Acheron Project's open-source, freely available tenkeyless (TKL) keyboard Printed Circuit Boards (PCB) which features:
+
+- No LED lighting
+- Solderless ("hotswap") MX switches support
+- Fixed layout for each variant
+
+* Keyboard Maintainer: [Gondolindrim](https://github.com/Gondolindrim)
+* Hardware Supported: open-source PCB using the [Joker template](https://acheronproject.com/joker_mcus/joker/). First units were manufactured using STM32F4x1 microcontroller;
+* Hardware Availability: open-source PCBs
+
+In order to flash this PCB, first build the default layout (after setting up your build environment):
+
+ make acheron/themis/<revision>:default
+
+After building or downloading the firmware, put the PCB into DFU mode by holding the reset button for at least five seconds and upload the firmware onto the microcontroller through a utility like `dfu-util` or QMK Toolbox. Alternatively, you can build and flash using:
+
+ make acheron/themis/<revision>: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).
