+# QMK CLI
+
+This page describes how to setup and use the QMK CLI.
+
+# Overview
+
+The QMK CLI makes building and working with QMK keyboards easier. We have provided a number of commands to help you work with QMK:
+
+* `qmk compile-json`
+
+# Setup
+
+Simply add the `qmk_firmware/bin` directory to your `PATH`. You can run the `qmk` commands from any directory.
+
+```
+export PATH=$PATH:$HOME/qmk_firmware/bin
+```
+
+You may want to add this to your `.profile`, `.bash_profile`, `.zsh_profile`, or other shell startup scripts.
+
+# Commands
+
+## `qmk compile-json`
+
+This command allows you to compile JSON files you have downloaded from <https://config.qmk.fm>.
+
+**Usage**:
+
+```
+qmk compile-json mine.json
+```

+# Coding Conventions (C)
+
+Most of our style is pretty easy to pick up on, but right now it's not entirely consistent. You should match the style of the code surrounding your change, but if that code is inconsistent or unclear use the following guidelines:
+
+* We indent using four (4) spaces (soft tabs)
+* We use a modified One True Brace Style
+  * Opening Brace: At the end of the same line as the statement that opens the block
+  * Closing Brace: Lined up with the first character of the statement that opens the block
+  * Else If: Place the closing brace at the beginning of the line and the next opening brace at the end of the same line.
+  * Optional Braces: Always include optional braces.
+    * Good: if (condition) { return false; }
+    * Bad: if (condition) return false;
+* We encourage use of C style comments: `/* */`
+  * Think of them as a story describing the feature
+  * Use them liberally to explain why particular decisions were made.
+  * Do not write obvious comments
+  * If you not sure if a comment is obvious, go ahead and include it.
+* In general we don't wrap lines, they can be as long as needed. If you do choose to wrap lines please do not wrap any wider than 76 columns.
+* We use `#pragma once` at the start of header files rather than old-style include guards (`#ifndef THIS_FILE_H`, `#define THIS_FILE_H`, ..., `#endif`)
+* We accept both forms of preprocessor if's: `#ifdef DEFINED` and `#if defined(DEFINED)`
+  * If you are not sure which to prefer use the `#if defined(DEFINED)` form.
+  * Do not change existing code from one style to the other, except when moving to a multiple condition `#if`.
+  * Do not put whitespace between `#` and `if`.
+  * When deciding how (or if) to indent directives keep these points in mind:
+    * Readability is more important than consistency.
+    * Follow the file's existing style. If the file is mixed follow the style that makes sense for the section you are modifying.
+    * When choosing to indent you can follow the indention level of the surrounding C code, or preprocessor directives can have their own indent level. Choose the style that best communicates the intent of your code.
+
+Here is an example for easy reference:
+
+```c
+/* Enums for foo */
+enum foo_state {
+  FOO_BAR,
+  FOO_BAZ,
+};
+
+/* Returns a value */
+int foo(void) {
+  if (some_condition) {
+    return FOO_BAR;
+  } else {
+    return -1;
+  }
+}
+```

+# Auto-formatting with clang-format
+
+[Clang-format](https://clang.llvm.org/docs/ClangFormat.html) is part of LLVM and can automatically format your code for you, because ain't nobody got time to do it manually. We supply a configuration file for it that applies most of the coding conventions listed above. It will only change whitespace and newlines, so you will still have to remember to include optional braces yourself.
+
+Use the [full LLVM installer](http://llvm.org/builds/) to get clang-format on Windows, or use `sudo apt install clang-format` on Ubuntu.
+
+If you run it from the command-line, pass `-style=file` as an option and it will automatically find the .clang-format configuration file in the QMK root directory.
+
+If you use VSCode, the standard C/C++ plugin supports clang-format, alternatively there is a [separate extension](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.ClangFormat) for it.
+
+Some things (like LAYOUT macros) are destroyed by clang-format, so either don't run it on those files, or wrap the sensitive code in `// clang-format off` and `// clang-format on`.

+When all timers are in use for [audio](feature_audio.md), the backlight software PWM will not use a hardware timer, but instead will be triggered during the matrix scan. In this case the backlight doesn't support breathing and might show lighting artifacts (for instance flickering), because the PWM computation might not be called with enough timing precision.

+## Backlight On State
+
+Most backlight circuits are driven by an N-channel MOSFET or NPN transistor. This means that to turn the transistor *on* and light the LEDs, you must drive the backlight pin, connected to the gate or base, *high*.
+Sometimes, however, a P-channel MOSFET, or a PNP transistor is used. In this case, when the transistor is on, the pin is driven *low* instead.
+
+This functionality is configured at the keyboard level with the `BACKLIGHT_ON_STATE` define.
+
+## Multiple backlight pins
+
+Most keyboards have only one backlight pin which control all backlight LEDs (especially if the backlight is connected to an hardware PWM pin).
+In software PWM, it is possible to define multiple backlight pins. All those pins will be turned on and off at the same time during the PWM duty cycle.
+This feature allows to set for instance the Caps Lock LED (or any other controllable LED) brightness at the same level as the other LEDs of the backlight. This is useful if you have mapped LCTRL in place of Caps Lock and you need the Caps Lock LED to be part of the backlight instead of being activated when Caps Lock is on.
+
+To activate multiple backlight pins, you need to add something like this to your user `config.h`:
+
+~~~c
+#define BACKLIGHT_LED_COUNT 2
+#undef BACKLIGHT_PIN
+#define BACKLIGHT_PINS { F5, B2 }
+~~~
 
 ## Hardware PWM Implementation
 
@@ -53,6 +101,15 @@ In this way `OCRxx` essentially controls the duty cycle of the LEDs, and thus th
 The breathing effect is achieved by registering an interrupt handler for `TIMER1_OVF_vect` that is called whenever the counter resets, roughly 244 times per second.
 In this handler, the value of an incrementing counter is mapped onto a precomputed brightness curve. To turn off breathing, the interrupt handler is simply disabled, and the brightness reset to the level stored in EEPROM.
 
+## Software PWM Implementation
+
+When `BACKLIGHT_PIN` is not set to a hardware backlight pin, QMK will use a hardware timer configured to trigger software interrupts. This time will count up to `ICRx` (by default `0xFFFF`) before resetting to 0.
+When resetting to 0, the CPU will fire an OVF (overflow) interrupt that will turn the LEDs on, starting the duty cycle.
+The desired brightness is calculated and stored in the `OCRxx` register. When the counter reaches this value, the CPU will fire a Compare Output match interrupt, which will turn the LEDs off.
+In this way `OCRxx` essentially controls the duty cycle of the LEDs, and thus the brightness, where `0x0000` is completely off and `0xFFFF` is completely on.
+
+The breathing effect is the same as in the hardware PWM implementation.
