This page attempts to explain the basic information you need to know to work with the QMK project. It assumes that you are familiar with navigating a Unix shell, but does not assume you are familiar with C or with compiling using make.
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_core` folder. The QMK additions to the project may be found in the `quantum` folder. Keyboard projects may be found in the `keyboards` folder.
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) for more information.
Within the folder `keyboards`, its subfolder `handwired` and its vendor and manufacture subdirectories e.g. `clueboard` is a directory for each keyboard project, for example `qmk_firmware/keyboards/clueboard/2x1800`. Within it, you'll find the following structure:
In every keymap folder, the following files may be found. Only `keymap.c` is required, and if the rest of the files are not found the default options will be chosen.
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.
