+Transports
+==========================
+
+The fastboot daemon supports multiple transport backends concurrently. Each transport can be individually enabled via Kconfig.
+
+- **USB**: Native USB fastboot protocol. Requires :code:`CONFIG_USBFASTBOOT=y`. Host: :code:`fastboot -s <SN> <command>` or just :code:`fastboot <command>`
+- **TCP**: Fastboot TCP v1 protocol on port 5554. Requires :code:`CONFIG_NET_TCP=y`. Host: :code:`fastboot -s tcp:<device-ip>[:port] <command>`
+- **Serial**: UART transport using TCP v1 wire framing. Use ``socat`` on the host to bridge the serial port to a TCP socket. Host: :code:`fastboot -s tcp:<host>:<socat-port> <command>`
+
 Commands
 ==========================
