 ### `make` Targets
 
 * `:dfu-util`: Waits until an STM32 bootloader device is available, and then flashes the firmware.
-* `:dfu-util-split-left` and `:dfu-util-split-right`: Flashes the firmware as with `:avrdude`, but also sets the handedness setting in EEPROM. This is ideal for Proton-C-based split keyboards.

 * `:st-link-cli`: Allows you to flash the firmware via the ST-Link CLI utility, rather than dfu-util. Requires an ST-Link dongle.
 * `:st-flash`: Allows you to flash the firmware via the `st-flash` utility from [STLink Tools](https://github.com/stlink-org/stlink), rather than dfu-util. Requires an ST-Link dongle.

 ### `make` 构建目标
 
 * `:dfu-util`: 每5秒检测一次直到发现可用的STM32 bootloader设备，然后进行固件刷写。
-* `:dfu-util-split-left` 和 `:dfu-util-split-right`: 同 `:avrdude` 一样会刷写固件，但额外地会设置手性设置到EEPROM中，对于基于Proton-C的分体式键盘这是理想的方法。
