## Installation
Put your keyboard into bootloader mode, either by hitting the `RESET` keycode (which may be on a different layer), or by pressing the reset switch that's usually located on the underside of the board. If your keyboard has neither, try holding Escape or Space+`B` as you plug it in (see the [Bootmagic Lite](feature_bootmagic.md) docs for more details). Some boards use [Command](feature_command.md) instead of Bootmagic; in this case, you can enter bootloader mode by hitting Left Shift+Right Shift+`B` or Left Shift+Right Shift+Escape at any point while the keyboard is plugged in.
Put your keyboard into bootloader mode, either by hitting the `QK_BOOT` keycode (which may be on a different layer), or by pressing the reset switch that's usually located on the underside of the board. If your keyboard has neither, try holding Escape or Space+`B` as you plug it in (see the [Bootmagic Lite](feature_bootmagic.md) docs for more details). Some boards use [Command](feature_command.md) instead of Bootmagic; in this case, you can enter bootloader mode by hitting Left Shift+Right Shift+`B` or Left Shift+Right Shift+Escape at any point while the keyboard is plugged in.
Some keyboards may have specific instructions for entering the bootloader. For example, the [Bootmagic Lite](feature_bootmagic.md) key (default: Escape) might be on a different key, e.g. Left Control; or the magic combination for Command (default: Left Shift+Right Shift) might require you to hold something else, e.g. Left Control+Right Control. Refer to the board's README file if you are unsure.
To put a device in bootloader mode with USBaspLoader, tap the `RESET` button while holding down the `BOOT` button.
1. Enter the bootloader using any of the following methods:
* Press the `RESET` keycode
* Press the `QK_BOOT` keycode
* Press the `RESET` button on the PCB if available
* Short RST to GND quickly
2. Wait for the OS to detect the device
