 ## LEDs
 Keyboard has 5 LEDs with common anode. Their cathodes are connected to R10–R14 resistors (you may want to replace them to adjust LED brightness for 3.3V voltage). Add 5 wire jumpers to connect them to the corresponding traces.

+Asterisk sign designates pins of the Teensy that don't align properly with PCB and need to be rewired.
+
+1. Compile and flash the firmware: `qmk compile -kb handwired/sono1/t2pp:default:flash`. Press the reset button on Teensy to launch the bootloader.
+2. You will need to solder several pin headers to Teensy: two 7 pin headers (C0–C7, D5–B7), 8 pin (F0–F7) and 4 pin (B1—B4). 
+3. Solder the Teensy to keyboard's PCB. You will need to manually reroute only 3 pins.

 ## Keymap
 'CUR LOCK' key on Sono2 numpad has locking switch by default (Alps SKCL lock). QMK [supports mechanical locking switches](https://docs.qmk.fm/#/faq_keymap?id=mechanical-lock-switch-support) for CapsLock, NumLock and ScrollLock keycodes.
+
+There is 'debug' keymap which doesn't output any scancodes, but displays row and column numbers of pressed buttons to console (hid_listen or QMK Toolbox).
