	93	+	## Layout support
	94	+
	95	+	Evil Crow Keylogger supports several layouts, the en_us layout is by default.
	96	+
	97	+	Set up a new layout:
	98	+
	99	+	* 0.- Open Keyboard/src/Keyboard.cpp with a text editor
	100	+
	101	+	* 1.- Change #define kbd_en_us to another layout. Example: #define kbd_es_es
	102	+
	103	+	You can use:
	104	+	- kbd_be_be
	105	+	- kbd_cz_cz
	106	+	- kbd_da_dk
	107	+	- kbd_de_de
	108	+	- kbd_en_us
	109	+	- kbd_es_es
	110	+	- kbd_fi_fi
	111	+	- kbd_fr_fr
	112	+	- kbd_it_it
	113	+	- kbd_pt_pt
	114	+	- kbd_tr_tr
	115	+
	116	+	* 2.- Save and close Keyboard.cpp
	117	+
