QMK is a fork of [Jun Wako](https://github.com/tmk)'s [tmk_keyboard](https://github.com/tmk/tmk_keyboard) project. The original TMK code, with modifications, can be found in the `tmk` folder. The QMK additions to the project may be found in the `quantum` folder. Keyboard projects may be found in the `handwired` and `keyboard` folders.
+### Userspace Structure
+
+Within the folder `users` is a directory for each user. This is a place for users to put code that they might use between keyboards. See the docs for [Userspace feature](feature_userspace.md) for more information.

### Keyboard Project Structure
Within the folder `keyboards` and its subfolder `handwired` is a directory for each keyboard project, for example `qmk_firmware/keyboards/clueboard`. Within it you'll find the following structure:
# The `config.h` File
-There are 2 `config.h` locations:
+There are 3 possible `config.h` locations:
* keyboard (`/keyboards/<keyboard>/config.h`)
+* userspace (`/users/<user>/config.h`)
* keymap (`/keyboards/<keyboard>/keymaps/<keymap>/config.h`)
-If the keymap `config.h` exists, that file is included by the build system and the keyboard `config.h` is not included. If you wish to override settings in your keymap's `config.h` you will need to include some glue code:
+The build system automatically picks up the config files in the above order. If you wish to override any setting set by a previous `config.h` you will need to first include some boilerplate code for the settings you wish to change.
```
-#ifndef CONFIG_USER_H
-#define CONFIG_USER_H
-
-#include "config_common.h"
+#pragma once
```
-If you want to override a setting from the parent `config.h` file, you need to `#undef` and then `#define` the setting again, like this:
+Then to override a setting from the previous `config.h` file you must `#undef` and then `#define` the setting again.
+
+The boilerplate code and setting look like this together:
+
+```
+#pragma once
-```c
+// overrides go here!
#undef MY_SETTING
#define MY_SETTING 4
```
