Fix wrong key when "Music Map" is used with MAJOR_MODE. (#11234)

With MAJOR_MODE (= major scale), keys in one octave is not 12 but 7.
To solve this problem, change divisor number from 12 to 7 at %(Modulo) and /(Division).

NOTE:
The last 12 represents half step keys in one octave for pitch calculation.

+# QMK Breaking Change - 2020 Nov 28 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.

+#### Reduce Helix keyboard build variation ([#8669](https://github.com/qmk/qmk_firmware/pull/8669))
+
+The build commands for the Helix keyboard are:
+
+```
+make <helix_build_name>:<keymap_name>
+```
+
+For `<helix_build_name>`, specify the one in the rightmost column of the table below, such as `helix`,` helix/pico`.

-# LED Control
-
-QMK provides methods to read 5 of the LEDs defined in the HID spec:
-
-* Num Lock
-* Caps Lock
-* Scroll Lock
-* Compose
-* Kana
-
-There are two ways to get the lock LED state:
-
-* by implementing `bool led_update_kb(led_t led_state)` or `_user(led_t led_state)`; or
-* by calling `led_t host_keyboard_led_state()`
-
-!> `host_keyboard_led_state()` may already reflect a new value before `led_update_user()` is called.
-
-Two more deprecated functions exist that provide the LED state as a `uint8_t`:
-
-* `uint8_t led_set_kb(uint8_t usb_led)` and `_user(uint8_t usb_led)`
-* `uint8_t host_keyboard_leds()`
-
-## `led_update_user()`
-
-This function will be called when the state of one of those 5 LEDs changes. It receives the LED state as a struct parameter.
-
-By convention, return `true` from `led_update_user()` to get the `led_update_kb()` hook to run its code, and
-return `false` when you would prefer not to run the code in `led_update_kb()`.
-
-Some examples include:
-
-  - overriding the LEDs to use them for something else like layer indication
-    - return `false` because you do not want the `_kb()` function to run, as it would override your layer behavior.
-  - play a sound when an LED turns on or off.
-    - return `true` because you want the `_kb` function to run, and this is in addition to the default LED behavior.
-
-?> Because the `led_set_*` functions return `void` instead of `bool`, they do not allow for overriding the keyboard LED control, and thus it's recommended to use `led_update_*` instead.
-
-### Example `led_update_kb()` Implementation
-
-```c
-bool led_update_kb(led_t led_state) {
-    bool res = led_update_user(led_state);
-    if(res) {
-        // writePin sets the pin high for 1 and low for 0.
-        // In this example the pins are inverted, setting
-        // it low/0 turns it on, and high/1 turns the LED off.
-        // This behavior depends on whether the LED is between the pin
-        // and VCC or the pin and GND.
-        writePin(B0, !led_state.num_lock);
-        writePin(B1, !led_state.caps_lock);
-        writePin(B2, !led_state.scroll_lock);
-        writePin(B3, !led_state.compose);
-        writePin(B4, !led_state.kana);
-    }
-    return res;
-}
-```
-
-### Example `led_update_user()` Implementation
-
-This incomplete example would play a sound if Caps Lock is turned on or off. It returns `true`, because you also want the LEDs to maintain their state.
-
-```c
-#ifdef AUDIO_ENABLE
-  float caps_on[][2] = SONG(CAPS_LOCK_ON_SOUND);
-  float caps_off[][2] = SONG(CAPS_LOCK_OFF_SOUND);
-#endif
-
-bool led_update_user(led_t led_state) {
-    #ifdef AUDIO_ENABLE
-    static uint8_t caps_state = 0;
-    if (caps_state != led_state.caps_lock) {
-        led_state.caps_lock ? PLAY_SONG(caps_on) : PLAY_SONG(caps_off);
-        caps_state = led_state.caps_lock;
-    }
-    #endif
-    return true;
-}
-```
-
-### `led_update_*` Function Documentation
-
-* Keyboard/Revision: `bool led_update_kb(led_t led_state)`
-* Keymap: `bool led_update_user(led_t led_state)`
-
-## `host_keyboard_led_state()`
-
-Call this function to get the last received LED state as a `led_t`. This is useful for reading the LED state outside `led_update_*`, e.g. in [`matrix_scan_user()`](#matrix-scanning-code).
-
-## Setting Physical LED State
-
-Some keyboard implementations provide convenience methods for setting the state of the physical LEDs.
-
-### Ergodox Boards
-
-The Ergodox implementations provide `ergodox_right_led_1`/`2`/`3_on`/`off()` to turn individual LEDs on or off, as well as `ergodox_right_led_on`/`off(uint8_t led)` to turn them on or off by their index.
-
-In addition, it is possible to specify the brightness level of all LEDs with `ergodox_led_all_set(uint8_t n)`; of individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`; or by index with `ergodox_right_led_set(uint8_t led, uint8_t n)`.
-
-Ergodox boards also define `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness (which is the default).

 You should use this function if you need custom matrix scanning code. It can also be used for custom status output (such as LEDs or a display) or other functionality that you want to trigger regularly even when the user isn't typing.

+* Keymap: `void housekeeping_task_user(void)`
+
+This function gets called at the end of all QMK processing, before starting the next iteration. You can safely assume that QMK has dealt with the last matrix scan at the time that these functions are invoked -- layer states have been updated, USB reports have been sent, LEDs have been updated, and displays have been drawn.

+Similar to `matrix_scan_*`, these are called as often as the MCU can handle. To keep your board responsive, it's suggested to do as little as possible during these function calls, potentially throtting their behaviour if you do indeed require implementing something special.

 When you tap a key, it stays depressed for a short period of time before it is
 then released. This depressed time is a different length for everyone. Auto Shift
 defines a constant `AUTO_SHIFT_TIMEOUT` which is typically set to twice your
-normal pressed state time. When you press a key, a timer starts and then stops
-when you release the key. If the time depressed is greater than or equal to the

+normal pressed state time. When you press a key, a timer starts, and if you
+have not released the key after the `AUTO_SHIFT_TIMEOUT` period, then a shifted
+version of the key is emitted. If the time is less than the `AUTO_SHIFT_TIMEOUT`
+time, or you press another key, then the normal state is emitted.
+
+If `AUTO_SHIFT_REPEAT` is defined, there is keyrepeat support. Holding the key
+down will repeat the shifted key, though this can be disabled with
+`AUTO_SHIFT_NO_AUTO_REPEAT`. If you want to repeat the normal key, then tap it
+once then immediately (within `TAPPING_TERM`) hold it down again (this works
+with the shifted value as well if auto-repeat is disabled).
 
 ## Are There Limitations to Auto Shift?
 
 Yes, unfortunately.
 
-1. Key repeat will cease to work. For example, before if you wanted 20 'a'
-   characters, you could press and hold the 'a' key for a second or two. This no
-   longer works with Auto Shift because it is timing your depressed time instead
-   of emitting a depressed key state to your operating system.
-2. You will have characters that are shifted when you did not intend on shifting, and
-   other characters you wanted shifted, but were not. This simply comes down to
-   practice. As we get in a hurry, we think we have hit the key long enough
-   for a shifted version, but we did not. On the other hand, we may think we are
-   tapping the keys, but really we have held it for a little longer than
-   anticipated.

+
+Additionally, with keyrepeat the desired shift state can get mixed up. It will
+always 'belong' to the last key pressed. For example, keyrepeating a capital
+and then tapping something lowercase (whether or not it's an Auto Shift key)
+will result in the capital's *key* still being held, but shift not.

 Beware that some pins may be powered during bootloader (ie. A13 on the STM32F303 chip) and will result in the solenoid kept in the on state through the whole flashing process. This may overheat and damage the solenoid. If you find that the pin the solenoid is connected to is triggering the solenoid during bootloader/DFU, select another pin.

+# LED Indicators
+
+QMK provides methods to read 5 of the LEDs defined in the HID spec:
+
+* Num Lock
+* Caps Lock
+* Scroll Lock
+* Compose
+* Kana
+
+There are three ways to get the lock LED state:
+* by specifying configuration options within `config.h`
+* by implementing `bool led_update_kb(led_t led_state)` or `_user(led_t led_state)`; or
+* by calling `led_t host_keyboard_led_state()`
+
+!> `host_keyboard_led_state()` may already reflect a new value before `led_update_user()` is called.
+
+Two more deprecated functions exist that provide the LED state as a `uint8_t`:
+
+* `uint8_t led_set_kb(uint8_t usb_led)` and `_user(uint8_t usb_led)`
+* `uint8_t host_keyboard_leds()`
+
+## Configuration Options
+
+To configure the indicators, `#define` these in your `config.h`:
+
+|Define               |Default      |Description                                |

+|`LED_PIN_ON_STATE`   |`1`          |The state of the indicator pins when the LED is "on" - `1` for high, `0` for low|
+
+Unless you are designing your own keyboard, you generally should not need to change the above config options.
+
+## `led_update_*()`
+
+When the configuration options do not provide enough flexibility, the API hooks provided allow custom control of the LED behavior. These functions will be called when the state of one of those 5 LEDs changes. It receives the LED state as a struct parameter.
+
+By convention, return `true` from `led_update_user()` to get the `led_update_kb()` hook to run its code, and
+return `false` when you would prefer not to run the code in `led_update_kb()`.
+
+Some examples include:
+
+  - overriding the LEDs to use them for something else like layer indication
+    - return `false` because you do not want the `_kb()` function to run, as it would override your layer behavior.
+  - play a sound when an LED turns on or off.
+    - return `true` because you want the `_kb` function to run, and this is in addition to the default LED behavior.
+
+?> Because the `led_set_*` functions return `void` instead of `bool`, they do not allow for overriding the keyboard LED control, and thus it's recommended to use `led_update_*` instead.
+
+### Example `led_update_kb()` Implementation
+
+```c
+bool led_update_kb(led_t led_state) {
+    bool res = led_update_user(led_state);
+    if(res) {
+        // writePin sets the pin high for 1 and low for 0.
+        // In this example the pins are inverted, setting
+        // it low/0 turns it on, and high/1 turns the LED off.
+        // This behavior depends on whether the LED is between the pin
+        // and VCC or the pin and GND.
+        writePin(B0, !led_state.num_lock);
+        writePin(B1, !led_state.caps_lock);
+        writePin(B2, !led_state.scroll_lock);
+        writePin(B3, !led_state.compose);
+        writePin(B4, !led_state.kana);
+    }
+    return res;
+}
+```
+
+### Example `led_update_user()` Implementation
+
+This incomplete example would play a sound if Caps Lock is turned on or off. It returns `true`, because you also want the LEDs to maintain their state.
+
+```c
+#ifdef AUDIO_ENABLE
+  float caps_on[][2] = SONG(CAPS_LOCK_ON_SOUND);
+  float caps_off[][2] = SONG(CAPS_LOCK_OFF_SOUND);
+#endif
+
+bool led_update_user(led_t led_state) {
+    #ifdef AUDIO_ENABLE
+    static uint8_t caps_state = 0;
+    if (caps_state != led_state.caps_lock) {
+        led_state.caps_lock ? PLAY_SONG(caps_on) : PLAY_SONG(caps_off);
+        caps_state = led_state.caps_lock;
+    }
+    #endif
+    return true;
+}
+```
+
+### `led_update_*` Function Documentation
+
+* Keyboard/Revision: `bool led_update_kb(led_t led_state)`
+* Keymap: `bool led_update_user(led_t led_state)`
+
+## `host_keyboard_led_state()`
+
+Call this function to get the last received LED state as a `led_t`. This is useful for reading the LED state outside `led_update_*`, e.g. in [`matrix_scan_user()`](#matrix-scanning-code).
+
+## Setting Physical LED State
+
+Some keyboard implementations provide convenience methods for setting the state of the physical LEDs.
+
+### Ergodox Boards
+
+The Ergodox implementations provide `ergodox_right_led_1`/`2`/`3_on`/`off()` to turn individual LEDs on or off, as well as `ergodox_right_led_on`/`off(uint8_t led)` to turn them on or off by their index.
+
+In addition, it is possible to specify the brightness level of all LEDs with `ergodox_led_all_set(uint8_t n)`; of individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`; or by index with `ergodox_right_led_set(uint8_t led, uint8_t n)`.
+
+Ergodox boards also define `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness (which is the default).

+# Sequencer
+
+Since QMK has experimental support for MIDI, you can now turn your keyboard into a [step sequencer](https://en.wikipedia.org/wiki/Music_sequencer#Step_sequencers)!
+
+!> **IMPORTANT:** This feature is highly experimental, it has only been tested on a Planck EZ so far. Also, the scope will be limited to support the drum machine use-case to start with.
+
+## Enable the step sequencer
+
+Add the following line to your `rules.mk`:
+
+```make
+SEQUENCER_ENABLE = yes
+```
+
+By default the sequencer has 16 steps, but you can override this setting in your `config.h`:
+
+```c
+#define SEQUENCER_STEPS 32
+```
+
+## Tracks
+
+You can program up to 8 independent tracks with the step sequencer. Select the tracks you want to edit, enable or disable some steps, and start the sequence!
+
+## Resolutions
+
+While the tempo defines the absolute speed at which the sequencer goes through the steps, the resolution defines the granularity of these steps (from coarser to finer).
+
+|Resolution   |Description            |
+|----------   |-----------            |
+|`SQ_RES_2`   |Every other beat       |

+## Hardware Considerations and Mods
+
+While most any Pro Micro can be used, micro controllers like the AVR Teensys and most (if not all) ARM boards require the Split USB Detect.
+
+However, with the Teensy 2.0 and Teensy++ 2.0, there is a simple hardware mod that you can perform to add VBUS detection, so you don't need the Split USB detection option.
+
+You'll only need a few things:
+
+* A knife (x-acto knife, ideally)
+* A solder station or hot air station
+* An appropriate Schottky diode, such as the [PMEG2005EH](https://www.digikey.com/en/products/detail/nexperia-usa-inc/PMEG2005EH,115/1589924)
+
+You'll need to cut the small trace between the 5V and center pads on the back of the Teensy.
+
+Once you have done that, you will want to solder the diode from the 5V pad to the center pad.
+
+You may need to use the 5V pad from the regulator block above as the pads were too small and placed too closely together to place the Schottky diode properly.

 Since starting, QMK has grown by leaps and bounds thanks to people like you who contribute to creating and maintaining our community keyboards. As we've grown we've discovered some patterns that work well, and ask that you conform to them to make it easier for other people to benefit from your hard work.
 
 
+## Use QMK Lint
+
+We have provided a tool, `qmk lint`, which will let you check over your keyboard for problems. We suggest using it frequently while working on your keyboard and keymap. 
+
+Example passing check:
+
+```
+$ qmk lint -kb rominronin/katana60/rev2

 ## Naming Your Keyboard/Project
 
 All keyboard names are in lower case, consisting only of letters, numbers, and underscore (`_`). Names may not begin with an underscore. Forward slash (`/`) is used as a sub-folder separation character.

 ## Advanced Settings :id=advanced-settings
 
 Each microcontroller can have multiple advanced settings regarding its GPIO. This abstraction layer does not limit the use of architecture-specific functions. Advanced users should consult the datasheet of their desired device and include any needed libraries. For AVR, the standard avr/io.h library is used; for STM32, the ChibiOS [PAL library](http://chibios.sourceforge.net/docs3/hal/group___p_a_l.html) is used.

+## Atomic Operation
+
+The above functions are not always guaranteed to work atomically. Therefore, if you want to prevent interruptions in the middle of operations when using multiple combinations of the above functions, use the following `ATOMIC_BLOCK_FORCEON` macro.
+
+eg.
+```c
+void some_function() {
+     // some process
+     ATOMIC_BLOCK_FORCEON {
+        // Atomic Processing
+     }
+     // some process
+}
+```
+
+`ATOMIC_BLOCK_FORCEON` forces interrupts to be disabled before the block is executed, without regard to whether they are enabled or disabled. Then, after the block is executed, the interrupt is enabled.
+
+Note that `ATOMIC_BLOCK_FORCEON` can therefore be used if you know that interrupts are enabled before the execution of the block, or if you know that it is OK to enable interrupts at the completion of the block.

+さらに、LED の明度を指定することができます。全ての LED に同じ明度を指定するなら `ergodox_led_all_set(uint8_t n)` を使い、個別の LED の明度を指定するなら `ergodox_right_led_1`/`2`/`3_set(uint8_t n)` を使い、LED のインデックスを指定して明度を指定するには  `ergodox_right_led_set(uint8_t led, uint8_t n)` を使います。

+
+Raw HID は、HID インタフェースを介して QMK とホストコンピュータ間の双方向通信を可能にします。これには、キーマップをその場で切り替えたり、RGB LED の色とモードを変更したりなど、多くの潜在的な使用方法があります。
+
+キーボードで raw HID を機能させるには、2つの主要なコンポーネントがあります。
+
+## キーボードファームウェア
+
+ファームウェアの実装はとても簡単です。
+`rules.mk` に以下を追加します:
+
+```make
+RAW_ENABLE = yes
+```
+
+`keymap.c` に `"raw_hid.h"` を include し、以下を実装します:
+
+```C
+void raw_hid_receive(uint8_t *data, uint8_t length) {
+    // ここにコードを書きます。data はホストから受信したパケットです。
+}
+```
+
+`"raw_hid.h"` ヘッダは、キーボードからホストにパケットを送信できる `void raw_hid_send(uint8_t *data, uint8_t length);` も宣言します。例として、全てのデータをホストに返すことで、ホストアプリケーションを構築する時のデバッグに使うこともできます。
+
+```C
+void raw_hid_receive(uint8_t *data, uint8_t length) {
+    raw_hid_send(data, length);
+}
+```
+
+`raw_hid_receive` はホストから最大長 `RAW_EPSIZE` の可変サイズのパケットを受信することができます。一方、`raw_hid_send` はパケットを厳密に `RAW_EPSIZE` の長さで送信するため、長さ `RAW_EPSIZE` のデータを使う必要があります。
+
+ホスト側での作業を進める前に、raw 対応のファームウェアを書き込むようにしてください。
+
+## ホスト (Windows/macOS/Linux)
+
+これは幾つかの掘り下げが必要になるため、より複雑な部分です。
+
+ホストコンピュータを raw HID を使ってキーボードに接続するには、キーボードについての4つの情報が必要です。
+
+1. Vendor ID
+2. Product ID
+3. Usage Page
+4. Usage
+
+前半の2つは、キーボードのメインディレクトリにあるキーボードの `config.h` で、`VENDOR_ID` と `PRODUCT_ID` で簡単に見つかります。
+
+後半の2つは、キーボードのメインディレクトリにあるキーボードの `config.h` で、値を再定義することで上書きすることができます: `#define RAW_USAGE_PAGE 0xFF60` と `#define RAW_USAGE_ID 0x61`。
+
+デフォルトでは、**Usage Page** は `0xFF60` で、**Usage** は `0x61` です。
+
+### ホストの構築
+
+独自に作成したくない場合は、利用可能な HID 実装ライブラリがある任意の言語を使ってホストを構築することができます。人気のある言語でよく使われるライブラリは以下の通りです:
+
+* Node: [node-hid](https://github.com/node-hid/node-hid)。
+* C: [hidapi](https://github.com/libusb/hidapi)。
+* Java: [purejavahidapi](https://github.com/nyholku/purejavahidapi) と [hid4java](https://github.com/gary-rowe/hid4java)。
+* Python: [pyhidapi](https://pypi.org/project/hid/)。
+
+これは完全なクロスプラットフォームのリストではありませんが、最初に始めるのに十分なはずです。raw HID を使うための特別な要件は無いため、どの HID ライブラリでも動作するはずです。
+
+これで、キーボードへの HID インタフェースを開くために必要な4つの情報全てが揃いました。必要なのは、ライブラリの利用可能な関数を使って ID パラメータを使ってデバイスを開くことだけです。
+
+Vendor ID と Product ID はデバイスを開くために実際には必要ないことに注意してください。それらは接続した多くの HID デバイスから特定のデバイスをフィルターするためだけに使われます。多くのライブラリでは、代わりに製品名と製造元名を使ってデバイスを開くオプションがあります。`node-hid` が代表的な例です。これは USB ハブが組み込まれているデバイスや、同じ製品名または同じ製造元の複数のインタフェースがある特別な HID インタフェースで問題になります。Product ID と Vendor ID を合わせると単一のインタフェースの固有名を作成できるため、この問題を防げます。したがって、ライブラリで必要が無い場合でも、この問題を防ぐためにそれらを使うことをお勧めします。
+ただし、Vendor ID や Product ID と異なり、Usage Page と Usage は通信を成功させるために必要です。
+
+言うまでもなく、使っているライブラリに関係なく、終了したらインタフェースを必ず閉じる必要があります。オペレーティングシステムと特定の環境によっては、明示的に接続が閉じられていない場合、後で他のクライアントまたは同じクライアントの他のインスタンスに接続しなおした時に問題が発生する可能性があります。

+
+## QMK Firmware 란?
+
+QMK(*Quantum Mechanical Keyboard 양자 기계식 키보드*)란 QMK 컴워어, QMK 툴박스, qmk.fm 를 관리하고 있는 오픈소스 커뮤니티 입니다. QMK펌웨어는 [tmk\_keyboard](http://github.com/tmk/tmk_keyboard)를 바탕으로 만들어진 키보드펌웨어이며, Atmel AVR컨트롤러와 [OLKB 제품군](http://olkb.com) [ErgoDox EZ](http://www.ergodox-ez.com), 그리고 [Clueboard 제품군](http://clueboard.co/) 이용할때 매우 편리합니다. 또한 QMK는 ChibiOS를 사용하여 ARM기반의 컨트롤러로도 사용할수 있습니다. 마지막으로 QMK는 커스텀회로와 핸드와이어드 키보드을 작동시키는데에도 사용가능합니다.
+
+
+## 설치하기
+
+만약 당신이 QMK에 키보드, 키맵, 또는 새로운 기능을 추가하고싶다면, 가장쉬운 방법은 Github를 통해 [저장소(REPO)를 추가하고]((https://github.com/qmk/qmk_firmware#fork-destination-box)) 로컬에서 변화 또는 수정하고, [PULL REQUEST](https://github.com/qmk/qmk_firmware/pulls)을 통해 업로드 할수 있습니다.
+
+또다른 방법으로는, 직접 파일들 로컬로 다운로드 하거나([zip](https://github.com/qmk/qmk_firmware/zipball/master), [tar](https://github.com/qmk/qmk_firmware/tarball/master)), git (`git@github.com:qmk/qmk_firmware.git`), https (`https://github.com/qmk/qmk_firmware.git`)을 통해 클론을 만들수 있습니다.
+
+## 컴파일
+
+먼저 컴파일을 하기전 AVR 이나 ARM [개발환경](getting_started_build_tools.md)을 구축해야 합니다. 모든준비가 끝났다면 `make`를 다음과 같이 키보드와 키맵을 선택하여 컴파일 할 수 있습니다.
+
+    make planck/rev4:default
+
+이 커맨드는 `rev4`버전의 `planck`를 `default`키맵으로 컴파일 할것입니다. 다만 모든 키보드는 파일, 수정본 또는 세부프로젝트를 가지고있지 않음으로 수정본 부분을 생략될수 있습니다.
+
+    make preonic:default
+
+## 커스터마이징
+
+QMK는 사용할 수 있는 매우 다양한 [기능](features.md)과 체계화된 [참고자료](http://docs.qmk.fm)들이 있습니다. 그중 대부분은 [키맵](keymap.md)을 수정하거나 [키코드](keycodes.md)를 변경하는데에 특화되어 있습니다.

+이 페이지는 QMK 컴파일 환경을 설치하는 방법을 설명합니다. 이 페이지는 AVR 프로세서들(예를 들면 atmega32u4와 비슷한)을 위한 가이드를 제공합니다
+
+<!-- FIXME: We should have ARM instructions somewhere. -->
+
+
+**노트:** 만약 당신이 처음 시작한다면 [입문자를 위한 가이드](newbs.md)페이지를 확인하세요.
+
+계속하기전에 당신의 서브모듈(외부라이브러리)이 최신인지 `make git-submodule`을 사용하여 확인하세요.
+
+## 리눅스
+
+당신이 항상 최신 파일을 가지고 있는지는 `sudo util/qmk_install.sh`을 이용하여 간단히 확인할 수 있습니다. 이 명령어는 당신이 필요한 모든 속성물(dependencies)를 설치할 것입니다. **이 명령어는 `apt-get upgrade`를 사용합니다**
+
+또한 당신의 직접 필요한 것들을 설치할 수도 있습니다. 하지만 이 자료는 항상 최신의 자료을 가지고 있지 않습니다.
+
+현재로써 필요한 것은 다음과 같습니다. 하지만 당신이 하는 작업에 따라 당신은 다음 패키지를 다 쓰지 않을 수도 있습니다. 또한 환경에 따라 모든 다음 패키지는 다른이름으로 존재하거나, 없을 수도 있습니다.
+
+```
+build-essential
+gcc
+unzip
+wget
+zip
+gcc-avr
+binutils-avr
+avr-libc
+dfu-programmer
+dfu-util
+gcc-arm-none-eabi
+binutils-arm-none-eabi
+libnewlib-arm-none-eabi
+git
+```
+
+당신이 사용하는 패키지 매니져에서 이러한 방법으로 설치하십시요.
+
+데비안 / 우분투 예시:
+
+    sudo apt-get update
+    sudo apt-get install gcc unzip wget zip gcc-avr binutils-avr avr-libc dfu-programmer dfu-util gcc-arm-none-eabi binutils-arm-none-eabi libnewlib-arm-none-eabi
+
+페도라 / 레드햇 예시:
+
+    sudo dnf install gcc unzip wget zip dfu-util dfu-programmer avr-gcc avr-libc binutils-avr32-linux-gnu arm-none-eabi-gcc-cs arm-none-eabi-binutils-cs arm-none-eabi-newlib
+    
+아치 / 맨자로(Manjaro) 예시:
+
+    pacman -S base-devel gcc unzip wget zip avr-gcc avr-binutils avr-libc dfu-util arm-none-eabi-gcc arm-none-eabi-binutils arm-none-eabi-newlib git dfu-programmer dfu-util
+
+## 닉스 (NIX)
+
+만약 당신이 [NixOS](https://nixos.org/)를 사용중이거나 NIX를 리눅스 또는 맥에서 사용중이라면 `nix-shell`를 root 디렉토리에서 사용하여 컴파일 환경의 구축할 수 있습니다.
+
+기본적으로 다음 커맨드는 AVR과 ARM 컴파일러를 설치할것입니다. 만약 필요 없다면 `avr` 또는 `arm`을 인수에서 해제할 수 있습니다.
+
+    nix-shell --arg arm false
+
+## 맥
+당신이 홈브루([homebrew](http://brew.sh/))를 사용한다면, 다음을 입력하세요.
+
+    brew tap osx-cross/avr
+    brew tap PX4/homebrew-px4
+    brew update
+    brew install avr-gcc@7
+    brew link --force avr-gcc@7
+    brew install dfu-programmer
+    brew install dfu-util
+    brew install gcc-arm-none-eabi
+    brew install avrdude
+
+이 방법을 가장 추천합니다. 만약 홈브루가 없다면 커맨드라인 환경에서 매우 편한 [Homebrew](http://brew.sh/)를 다운받는 것을 추천합니다. 참고로 `avr-gcc@7`를 설치하는 중 `make`과 `make install`는 대개 20분 넘게 걸리고 CPU 사용량이 높아집니다.
+
+## msys2를 사용하는 윈도우 (추천)
+윈도우 비스타 부터 최신버젼까지 가장추천되는 환경은 [msys2](http://www.msys2.org)를 이용하는 것입니다. (윈도우 7과 윈도우 10에서 모두 테스트되었음)
+
+* 이 사이트에 있는 설명을 이용해 msys2를 설치하세요: http://www.msys2.org
+* ``MSYS2 MingGW 64-bit`` 를 여세요
+* QMK폴더로 이동하세요. c드라이브 루트에 있는경우:
+ * `$ cd /c/qmk_firmware`
+* `util/qmk_install.sh`을 실행시키고 나오는데요 따라하세요
+
+### 크리에이터 업데이트
+만약 당신의 윈도우 10이 크리에이터 업데이트 버전 또는 더 높은 버전이라면 바로 컴파일과 프로그램 업로드(flashing)를 할 수 있습니다. 크리에이터 업데이트 전 버전이라면 컴파일만 가능합니다. 만약 당신이 잘 모르겠거나 업데이트된 버전이 아니라면 [이 링크](https://support.microsoft.com/en-us/instantanswers/d4efb316-79f0-1aa1-9ef3-dcada78f3fa0/get-the-windows-10-creators-update)를 확인해 보십시오.
+
+### 리눅스용 윈도우 하위 시스템 사용 (Windows10 Subsystem for Linux)
+크리에이터 업데이트에 추가로 만약 당신이 리눅스용 윈도우 하위 시스템이 필요하다면 이 링크에서 다운받으십시오: [설명](http://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/)
+
+만약 당신이 이미 리눅스용 윈도우 하위 시스템을 Anniversary업데이트를 통해 받았다면 이 링크에서 16.04LTS로 업데이트 하는것을 추천합니다. 왜냐하면 업데이트 없이는 일부키보드가 14.04LTS에 포함되있는 도구들로 컴파일되지 않을수 있기때문입니다 : [WSL 업데이트](https://betanews.com/2017/04/14/upgrade-windows-subsystem-for-linux/)
+
+
+### Git
+만약 당신이 이미 파일을 로컬로 복제하였다면 이 섹션을 무시하십시요.
+
+당신은 파일을 기본적인 git을 사용하여 로컬로 복제해야 합니다. **주의, WSL Git을 사용하면 안됩니다** [Git](https://git-scm.com/download/win) 이 링크에서 git을 다운받고 설치하십시오.
+그리고 [기본설정](https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup), 유저네임과 이메일을 설정하는 것은 만약 당신이 온라인에 기여할 계획이라면 매우 중요합니다.
+
+Git의 설치가 완료되었다면 Git Bash커맨드을 열고 당신의 복제 QMK파일이 있는 위치로 이동하고 `git clone --recurse-submodules https://github.com/qmk/qmk_firmware`를 실행 시키십니오. 이 커맨드는 새로운 `qmk_firmware`폴더를 이미 존재하는 것의 하위 폴더설정으로 생성할 것입니다.
+
+### 도구(Toolchain) 설정
+기본적으로 도구설정은 리눅스용 윈도우 하위 시스템이 설치될때 자동으로 설정됩니다. 하지만 수동적으로 하고 싶다면 여기 설명이 있습니다. (If you want to do everything manually, there are no other instructions than the scripts themselves, but you can always open issues and ask for more information. )
+
+1. "Bash On Ubuntu On Windows" 을 실행시키십시오.
+2. 당신이 `qmk_firmware`를 복제한 위치로 가십시오. WSL(리눅스용 윈도우 하위 시스템 사용)에서 `/mnt/`로 시작되는 패스를 찾으십시오. 즉 당신은 다음과 같은 형식으로 입력해야 합니다. `cd /mnt/c/path/to/qmk_firmware`  (Note that the paths start with `/mnt/`in the WSL, so you have to write for example `cd /mnt/c/path/to/qmk_firmware`.)
+3. `util/wsl_install.sh`를 실행시키고 화면에 나오는 지시를 따르십니오.
+4. Bash command window를 재실행 시키십시오.
+5. 이로써 당신은 컴파일과 프로그램 업로드(flashing)을 위한 준비가 모두 끝났습니다.
+
+### 중요한 참고사항
+*`util/wsl_install.sh` 명령어를 다시 실행시켜 최신 업데이트를 다운받을 수 있습니다.
+* QMK 폴더의 위치는 윈도우 파일시스템을 기반으로 해야 됩니다. WSL는 외부실행파일를 작동 시킬수 없기 때문이죠.
+* WSL의 Git은 윈도우용 Git과 **호환되지 않습니다**
+* 파일을 수정하는 것은 WSL안과 밖에서 모두 가능합니다 하지만 만약 .makefile 혹은 .sh를 수정한다면 유닉스 라인엔딩(Unix line endings)을 지원하는 에디터를 사용하는지 확인하십이오. 그렇지 않다면 컴파일이 되지않을 수도 있습니다.
+
+## 윈두우 (비스타 혹은 더 최신) (비추천)
+
+이 섹션은 윈도우 비스타 혹은 더 최신버젼을 위한 오래된 설명입니다. [MSYS2](#windows-with-msys2-recommended)를 사용하는 것을 더 추천합니다.
+
+1. WinAVR을 설치하였다면 먼저 삭제하십시오.
+2. [MHV AVR Tools](https://infernoembedded.com/sites/default/files/project/MHV_AVR_Tools_20131101.exe)을 설치하십시오. (Disable smatch, but **be sure to leave the option to add the tools to the PATH checked**)
+3. 만약 당신이 Infinity을 기반으로 하는 키보드에 프로그램 업로드를(flashing) 할거라면 dfu-util을 설치해야 합니다, [Input Club](https://github.com/kiibohd/controller/wiki/Loading-DFU-Firmware) 를 참고 하십시오.
+4. [MinGW](https://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download)를 설치하십시오. 설치중 윈도우화면에서 GUI 추가 설치 옵션을 해재하십니오. **기본 설치 위치를 바꾸지 마십시오.** 이 명령어는 기본위치를 기반으로 하고 있습니다.
+5. 레파지토리를 복제하십시오. [이 링크로 압축파일을 받고 앞축해제 하십시오.](https://github.com/qmk/qmk_firmware/archive/master.zip) 윈도우 탐색기에서 다운받은 파일을 여십시오.
+6. `\util` 폴더를 여십시오.
+7. `1-setup-path-win` .bat파일을 더블클릭해서 실행시키시오. 유저 계정 설정 변경을 허용해야될 수도 있습니다. 스페이스바를 눌러 설치가 성공적으로 완료되었다는 메세지를 닫을 수 있습니다.
+8. `2-setup-environment-win` .bat파일에 우클릭해서 '관리자 권한으로 실행'으로 실행시키십시오. 이 작업을 꽤 오래 걸릴 수도 있습니다. 또한 드라이버 설정을 승인해야 될 수도 있습니다. 하지만 이 모든것이 끝나면 당신의 시스템의 설정이 모두 끝났습니다.
+
+만약 이 작업을 하는데에 문제가 있어 도움받고 싶다면 *Win_Check_Output.txt*을 생성하는 것이 도움이 될것입니다. 이 파일은 `Win_Check.bat`을 `\util`폴더에서 실행시켜 생성할 수 있습니다.
+
+## 도커(Docker)
+만약 위작업들이 당신에게 좀 어렵게 느껴졌다면 도커(Docker)가 당신을 위한 최선일 수도 있습니다(의역). [Docker CE](https://docs.docker.com/install/#supported-platforms)를 설치한뒤 아래 커맨드를 `qmk_firmware` 디랙토리에서 실행시켜 키보드 또는 키맵을 생성시킵니다.
+```bash
+util/docker_build.sh keyboard:keymap
+# 예: util/docker_build.sh ergodox_ez:steno
+```
+이 커맨드는 원하는 키보드 또는 키맵을 컴파일하고 `.hex`또는 `.bin`파일을 프로그램 업로드를(flashing) 위해 QMK디랙토리에 생성할것입니다. 만약 `:keymap`이 생략된다면 `default`이 기본을로 사용됩니다. 참고로 여기서 사용되는 인수는 `make` 커맨드를 사용하여 컴파일할때와 동일합니다.
+
+
+또한 스크립트를 그냥 아무 인수 없이도 사용가능합니다. 그렇게 된다면 프로그램은 하나씩 자동으로 인수입력을 요구 할것입니다. 어쩌면 이방법이 더 쉬울 수도 있습니다.
+```bash
+util/docker_build.sh
+# 인수을 입력받습니다.(아무것도 쓰지 않고 놔두는면 기본값으로 설정됩니다)
+```
+
+다음과 같이 `target`를 사용하여 컴파일과 프로그램 업로드(flashing)을 동시에 할수도 있습니다.
+```bash
+util/docker_build.sh keyboard:keymap:target
+# 예: util/docker_build.sh planck/rev6:default:dfu-util
+```
+만약 당시이 리눅스를 사용한다면 이 커맨드들은 추가 설정 없이 바로 작동할 것입니다. 하지만 위도우 또는 맥 환경에서는 [Docker Machine](http://gw.tnode.com/docker/docker-machine-with-usb-support-on-windows-macos/)를 사용하여야 이 커맨드들을 사용가능합니다. Docker Machine설정은 꽤 지루하고 짜증남으로 추천하지 않고 [QMK Toolbox](https://github.com/qmk/qmk_toolbox)를 사용하는 것을 추천합니다.
+
+!> 윈도우에서 독커는 [Hyper-V](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v)을 활성화 설정하여야 사용가능합니다. 즉, 도커는 Hyper-V를 지원하지 않는 윈도우 7, 윈도우 8, 그리고 **윈도우 10 홈**과 같은 윈도우 버전에서 사용할수 없다는 것을 의미합니다.
+
+## Vagrant
+만약 컴웨어를 사용하는데 문제가 있다면 Vagrant라는 이름의 툴을 사용해 볼 수 있습니다. 이 툴은 가상환경을 세팅해줌과 동시에 컴웨어를 사용하는데에 필요한 모든 설정을 해줄 것입니다. OLKB는 가상환경에 파일을 호스팅하지 않습니다. [Vagrant 가이드](getting_started_vagrant.md)에서 더 많은 정보를 확인할 수 있습니다.

 Your computer keyboard has a processor inside of it, similar to the one inside your computer. This processor runs software that is responsible for detecting button presses and informing the computer when keys are pressed. QMK Firmware fills the role of that software, detecting button presses and passing that information on to the host computer. When you build your custom keymap, you are creating an executable program for your keyboard.

 Sometimes it's useful to print debug messages from within your [custom code](custom_quantum_functions.md). Doing so is pretty simple. Start by including `print.h` at the top of your file:

 After that you can use a few different print functions:
