 We are now ready to compile and use our own bootloader, kernel and root
 filesystem.

+\section{Attach the LCD cape}
+
+Switch off the board first, by pressing the \code{POWER} button until
+all the LEDs go off\footnote{That's strongly recommended by the board
+maker, to avoid hardware damage that can happen if the board is abruptly
+switched off.}.
+
+Now that we have successfully tested serial console, we are ready to
+attach the LCD4 cape provided by your instructor.
+
+Note that if you bought your own Beagle Bone Black board, you will have
+to {\bf gently} bend the serial headers using pliers, otherwise the
+serial cable won't fit between the board and the cape.
+
+There are two ways to connect the cape headers to the Bone Black
+headers, but only one actually fits, the \code{POWER} button of the cape
+sliding right between the board's RJ45 connector and power barrel
