-Flipper Zero's firmware consists of two components: Bootloader and main firmware. Bootloader controls firmware update process over USB. You need working bootloader installed before update firmware over USB.
+Flipper Zero's firmware consists of three components:
+
+- Core2 firmware - proprietary componenets by ST: FUS + radio stack.
+- Core1 Bootloader - controls basic hardware initialization and loads firmware
+- Core1 Firmware - HAL + OS + Drivers + Applications
+
+All 3 of them must be flashed in order described.
+
+## With STLink
+
+### Core2 flashing procedures
+
+Prerequisites:
+
+- Linux / MacOs
+- Terminal
+- STM32_Programmer_CLI added to $PATH
+
+One liner: `./flash_core2_ble.sh`
+
+### Core1 Bootloader + Firmware
+
+Prerequisites:
+
+- Linux / MacOs
+- Terminal
+- Arm gcc noneabi
+- openocd
+
+One liner: `./flash_core1_main.sh`
+
+## With USB DFU
