-### What is QMK Firmware? {#what-is-qmk-firmware}
 
 QMK (*Quantum Mechanical Keyboard*) is an open source community that maintains QMK Firmware, QMK Flasher, qmk.fm, and these docs. QMK Firmware is a keyboard firmware based on the [tmk\_keyboard](http://github.com/tmk/tmk_keyboard) with some useful features for Atmel AVR controllers, and more specifically, the [OLKB product line](http://olkb.com), the [ErgoDox EZ](http://www.ergodox-ez.com) keyboard, and the [Clueboard product line](http://clueboard.co/). It has also been ported to ARM chips using ChibiOS. You can use it to power your own hand-wired or custom keyboard PCB.

+## How to get it {#how-to-get-it}
 
 If you plan on contributing a keymap, keyboard, or features to QMK, the easiest thing to do is [fork the repo through Github](https://github.com/qmk/qmk_firmware#fork-destination-box), and clone your repo locally to make your changes, push them, then open a [Pull Request](https://github.com/qmk/qmk_firmware/pulls) from your fork.
 
 Otherwise, you can either download it directly ([zip](https://github.com/qmk/qmk_firmware/zipball/master), [tar](https://github.com/qmk/qmk_firmware/tarball/master)), or clone it via git (`git@github.com:qmk/qmk_firmware.git`), or https (`https://github.com/qmk/qmk_firmware.git`).

+If you have an idea for a custom feature or extra hardware connection, we'd love to accept it into QMK! 
+
+Before you put a lot of work into building your new feature you should make sure you are implementing it in the best way. You can get a basic understanding of QMK by reading [Understaning QMK](understanding_qmk.html), which will take you on a tour of the QMK program flow. From here you should talk to us to get a sense of the best way to implement your idea. There are two main ways to do this:
+
+* [Chat on Gitter](https://gitter.im/qmk/qmk_firmware)
+* [Open an Issue](https://github.com/qmk/qmk_firmware/issues/new)
+
+Once you have implemented your new feature you will generally submit a [pull request](https://github.com/qmk/qmk_firmware/pulls). Here are some things to keep in mind when creating one:

If you think it should be on by default, or reduces the size of the code, please talk with us about it.
 * **Compile locally before submitting** - hopefully this one is obvious, but things need to compile! Our Travis system will catch any issues, but it's generally faster for you to compile a few keyboards locally instead of waiting for the results to come back.
 * **Consider subprojects and different chip-bases** - there are several keyboards that have subprojects that have allow for slightly different configurations, and even different chip-bases. Try to make a feature supported in ARM and AVR, or automatically disabled in one that doesn't work.
-* **Explain your feature** - submitting a markdown write-up of what your feature does with your PR may be needed, and it will allow a collaborator to easily copy it into the wiki for documentation (after proofing and editing).
+* **Explain your feature** - Document it in `docs/`, either as a new file or as part of an existing file. If you don't document it other people won't be able to benefit from your hard work.
 * **Don't refactor code** - to maintain a clear vision of how things are laid out in QMK, we try to plan out refactors in-depth, and have a collaborator make the changes. If you have an idea for refactoring, or suggestions, [open an issue](https://github.com/qmk/qmk_firmware/issues).

+<!-- FIXME: We should have ARM instructions somewhere. -->
+
+# Windows 10
+
+## Creators Update
 If you have Windows 10 with Creators Update or later, you can build and flash the firmware directly. Before the Creators Update, only building was possible. If you don't have it yet or if are unsure, follow [these instructions](https://support.microsoft.com/en-us/instantanswers/d4efb316-79f0-1aa1-9ef3-dcada78f3fa0/get-the-windows-10-creators-update).

If you already have the Windows 10 Subsystem for Linux from the Anniversary update it's recommended that you [upgrade](https://betanews.com/2017/04/14/upgrade-windows-subsystem-for-linux/) it to 16.04LTS, because some keyboards don't compile with the toolchains included in 14.04LTS. Note that you need to know what your are doing if you chose the `sudo do-release-upgrade` method.
 
-#### Git
+## Git
 If you already have cloned the repository on your Windows file system you can ignore this section.
 
 You will need to clone the repository to your Windows file system using the normal Git for Windows and **not** the WSL Git. So if you haven't installed Git before, [download](https://git-scm.com/download/win) and install it. Then [set it up](https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup), it's important that you setup the e-mail and user name, especially if you are planning to contribute. 
 
 Once Git is installed, open the Git bash command and change the directory to where you want to clone QMK, note that you have to use forward slashes, and that your c drive is accessed like this `/c/path/to/where/you/want/to/go`. Then run `git clone --recurse-submodules https://github.com/qmk/qmk_firmware`, this will create a new folder `qmk_firmware` as a subfolder of the current one.

 * The WSL Git is **not** compatible with the Windows Git, so use the Windows Git Bash or a windows Git GUI for all Git operations
 * You can edit files either inside WSL or normally using Windows, but note that if you edit makefiles or shell scripts, make sure you are using an editor that saves the files with Unix line endings. Otherwise the compilation might not work.

 1. If you haven't already, obtain this repository ([https://github.com/qmk/qmk_firmware](https://github.com/qmk/qmk_firmware)). You can either download it as a zip file and extract it, or clone it using the command line tool git or the Github Desktop application.
 2. Open up a terminal or command prompt and navigate to the `qmk_firmware` folder using the `cd` command. The command prompt will typically open to your home directory. If, for example, you cloned the repository to your Documents folder, then you would type `cd Documents/qmk_firmware`. If you extracted the file from a zip, then it may be named `qmk_firmware-master` instead.
 3. To confirm that you're in the correct location, you can display the contents of your current folder using the `dir` command on Windows, or the `ls` command on Linux or Mac. You should see several files, including `readme.md` and a `quantum` folder. From here, you need to navigate to the appropriate folder under `keyboards/`. For example, if you're building for a Planck, run `cd keyboards/planck`.

+# Documentation Best Practices
+
+This page exists to document best practices when writing documentation for QMK. Following these guidelines will help to keep a consistent tone and style, which will in turn help other people more easily understand QMK.
+
+# Page Opening
+
+Your documentation page should generally start with an H1 heading, followed by a 1 paragrah description of what the user will find on this page. Keep in mind that this heading and paragraph will sit next to the Table of Contents, so keep the heading short and avoid long strings with no whitespace.
+
+Example:
+
+```
+# My Page Title
+
+This page covers my super cool feature. You can use this feature to make coffee, squeeze fresh oj, and have an egg mcmuffin and hashbrowns delivered from your local macca's by drone.
+```
+
+# Headings
+
+Your page should generally have multiple "H1" headings. Only H1 and H2 headings will included in the Table of Contents, so plan them out appropriately. Excess width should be avoided in H1 and H2 headings to prevent the Table of Contents from getting too wide.
+
+# Styled Hint Blocks
+
+You can have styled hint blocks drawn around text to draw attention to it.
+
+{% hint style='info' %}
+This uses \{\% hint style='info' \%\}
+{% endhint %}
+
+{% hint style='tip' %}

+## What is QMK?
 
+[QMK](https://github.com/qmk), short for Quantum Mechanical Keyboard, is a group of people building tools for custom keyboards. We started with the [QMK firmware](https://github.com/qmk/qmk_firmware), a heavily modified fork of [TMK](https://github.com/tmk/tmk_keyboard).

+## What Differences Are There Between QMK and TMK?
-- [[FAQ/Build]]
 
+TMK was originally designed and implemented by [Jun Wako](https://github.com/tmk). QMK started as [Jack Humbert's](https://github.com/jackhumbert) fork of TMK for the Planck. After a while Jack's fork had diverged quite a bit from TMK, and in 2015 Jack decided to rename his fork to QMK.
 
-# Keymap
+From a technical standpoint QMK builds upon TMK by adding several new features. Most notably QMK has expanded the number of available keycodes and uses these to implement advanced features like `S()`, `LCTL()`, and `MO()`. You can see a complete list of these keycodes in [Quantum Keycodes](quantum_keycodes.html).

-### Switching and toggling layers
+# Switching and toggling layers
 
 `MO(layer)` - momentary switch to *layer*. As soon as you let go of the key, the layer is deactivated and you pop back out to the previous layer. When you apply this to a key, that same key must be set as `KC_TRNS` on the destination layer. Otherwise, you won't make it back to the original layer when you release the key (and you'll get a keycode sent). You can only switch to layers *above* your current layer. If you're on layer 0 and you use `MO(1)`, that will switch to layer 1 just fine. But if you include `MO(3)` on layer 5, that won't do anything for you -- because layer 3 is lower than layer 5 on the stack.
 
-`OSL(layer)` - momentary switch to *layer*, as a one-shot operation. So if you have a key that's defined as `OSL(1)`, and you tap that key, then only the very next keystroke would come from layer 1. You would drop back to layer zero immediately after that one keystroke. That's handy if you have a layer full of custom shortcuts -- for example, a dedicated key for closing a window. So you tap your one-shot layer mod, then tap that magic 'close window' key, and keep typing like a boss. Layer 1 would remain active as long as you hold that key down, too (so you can use it like a momentary toggle-layer key with extra powers).
-
 `LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped. Like `MO()`, this only works upwards in the layer stack (`layer` must be higher than the current layer).
 
 `TG(layer)` - toggles a layer on or off. As with `MO()`, you should set this key as `KC_TRNS` in the destination layer so that tapping it again actually toggles back to the original layer. Only works upwards in the layer stack.

 `TT(layer)` - Layer Tap-Toggle. If you hold the key down, the layer becomes active, and then deactivates when you let go. And if you tap it, the layer simply becomes active (toggles on).

 You can think of QMK as no different from any other computer program. It is started, performs its tasks, and then ends. The entry point for the program is the `main()` function, just like it is on any other C program. However, for a newcomer to QMK it can be confusing because the `main()` function appears in multiple places, and it can be hard to tell which one to look at.
 
-The reason for this is the different platforms that QMK supports. The most common platform is `lufa`, which runs on AVR processors such at the atmega32u4. We also support `chibios`, `pjrc`, `vusb`, and `bluefruit`, and may support more in the future.

-Let's focus on AVR processors for the moment, which use the `lufa` platform. You can find the `main()` function in [tmk_core/protocol/lufa/lufa.c](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/protocol/lufa/lufa.c#L1129). If you browse through that function you'll find that it initializes any hardware that has been configured (including USB to the host) and then it starts the core part of the program with a [`while(1)`](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/protocol/lufa/lufa.c#L1182). This is [The Main Loop](#the_main_loop).

 ## The Main Loop
 
-This section of code is called "The Main Loop" because it's responsible for looping over the same set of instructions forever. This is where QMK dispatches out to the functions responsible for making the keyboard do everything it is supposed to. At first glance it can look like a lot of functionality but most of the time the code will be disabled by `#define`'s.

-This section of code handles the USB suspend state. This state is entered when the computer the keyboard is plugged into is suspended. In this state we don't do anything but wait for the computer we're plugged into to wake up.

-### `keyboard_task()`
 
 ```
     keyboard_task();
 ```
 
-This is where all the keyboard specific functionality is dispatched. The source code for `keyboard_task()` can be found in [tmk_core/common/keyboard.c](https://github.com/qmk/qmk_firmware/blob/master/tmk_core/common/keyboard.c#L154), and it is responsible for detecting changes in the matrix and turning LED's on and off.

 ##### State Change Detection
 
 The matrix scanning described above tells us the state of the matrix at a given moment, but your computer only wants to know about changes, it doesn't care about the current state. QMK stores the results from the last matrix scan and compares the results from this matrix to determine when a key has been pressed or released.
