$ make clean
+## WINAVR is obsolete
+It is no longer recommended and may cause some problem.
+See [Issue #99](https://github.com/tmk/tmk_keyboard/issues/99).
+
+## USB stack: LUFA or PJRC?
+Use **LUFA**.
+
+**PJRC** stack won't be supported actively anymore. There is no reason to hesitate to use LUFA except for binary size(about 1KB lager?). But **PJRC** is still very useful for debug and development purpose.
+See also [Issue #50](https://github.com/tmk/tmk_keyboard/issues/50) and [Issue #58](https://github.com/tmk/tmk_keyboard/issues/58).
+
+
+## Edit configuration but not change
+Try these.
+### 1. make clean
+This will be needed when you edit **config.h**.
+
+### 2. Remove Drivers from Device Manager(Windows)
+Windows only. Linux, OSX and other OS's doesn't require this. It looks like Windows keeps using driver installed when device was connected first time even after the device changes its configuration. To load proper drivers for new configuration you need to remove existent drivers from **Drvice Manager**.
+
+You will need this after editing `CONSOLE_ENABLE`, `NKRO_ENABLE`, `EXTRAKEY_ENABLE` or `MOUSEKEY_ENABLE` option in **Makefile**.
+
+
+# Keymap
+## Power key doesn't work
+Use `KC_PWR` instead of 'KC_POWER` or vice versa.
+- `KC_PWR` works with Windows and Linux, not with OSX.

# Degug Console
## hid_listen can't find device

-# NKRO
+# Miscellaneous
+## NKRO Doesn't work
+1. Build with this option of Makefile
+
+ NKRO_ENABLE = yes
+
+2. After boot keyboard may be in **boot mode**(6KRO), you will need to replug keyboard to enable NKRO.
+
+3. Or use `Magic` **N** command to toggle NKRO function.(`LShift+RShift+N` by default)
+
+
+
+## TrackPoint needs reset circuit(PS/2 mouse support)
+Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.

+## Can't read comlumn of matrix beyond 16
+Use `1UL<<16` intead of `1<<16` in `read_cols()` in **matrix.h** when your columns goes beyond 16.
+
+In C `1` means one of **int** type which is **16bit** in case of AVR so you can't shift left more than 15. You will get unexpected zero when you say `1<<16`. You have to use **unsigned long** type with `1UL`.

+
+## Pull-up Resistor
+In some case converters needed to have pull-up resistors to work correctly. Place the resistor between VCC and signal line in parallel.
+
+```
+Keyboard Conveter
+ ,------.
+5V------+------|VCC |
+ | | |
+ R | |
+ | | |
+Signal--+------|PD0 |
+ | |
+GND------------|GND |
+ `------'
+R: 1K Ohm resistor
+```
+
+
+## Arduino Micro's pin naming is confusing
+Note that Arduino Micro PCB marking is different from real AVR port name. D0 of Arduino Micro is not PD0, PD0 is D3. Check schematic yourself.

+
+## Bootloader jump doesn't work
+Properly configure boot section size in Makefile. With wrong section size bootloader won't probably start with **Magic command** and **Boot Magic**.
+- https://github.com/tmk/tmk_keyboard#magic-commands
+- https://github.com/tmk/tmk_keyboard#bootloader
+
+```
+# Boot Section Size in *bytes*
+# Teensy halfKay 512
+# Teensy++ halfKay 1024
+# Atmel DFU loader 4096 (TMK Alt Controller)
+# LUFA bootloader 4096
+# USBaspLoader 2048
+OPT_DEFS += -DBOOTLOADER_SIZE=4096

+
+
+## Special Extra key doesn't work(System, Audio control keys)
+You need to define `EXTRAKEY_ENABLE` in **makefile** to use them in TMK.
+```
+EXTRAKEY_ENABLE = yes # Audio control and System control
+```

+## Wakeup from sleep doesn't work
+In Windows check `Allow this device to wake the computer` setting in Power **Management property** tab of **Device Manager**. Also check BIOS setting.
