 ### Flash the board
 
-1. Put the board in bootloader mode by double tapping the reset button.<br/>
-   When the board is in bootloader mode, the user led (red) oscillates smoothly.
-
-
-2. Use `BOARD=feather-m0` with the `make` command.<br/>
-   Example with `hello-world` application:
+Use `BOARD=feather-m0` with the `make` command.<br/>
+Example with `hello-world` application:
 ```
      make BOARD=feather-m0 -C examples/hello-world flash
 ```
 
+@note     If the application crashes, automatic reflashing via USB, as explained
+          above won't be possible. In this case, the board must be set in
+          bootloader mode by double tapping the reset button before running the
+          flash command.
+
 ### Accessing STDIO via UART
 
-To access the STDIO of RIOT, a FTDI to USB converted needs to be plugged to
-the RX/TX pins on the board.
+STDIO of RIOT is directly available over the USB port.
+
+The `TERM_DELAY` environment variable can be used to add a delay (in second)
+before opening the serial terminal. The default value is 2s which should be
+enough in most of the situation.
