+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:
 
 * `keymaps/`: Different keymaps that can be built
 * `rules.mk`: The file that sets the default "make" options. Do not edit this file directly, instead use a keymap specific `rules.mk`.
 * `config.h`: The file that sets the default compile time options. Do not edit this file directly, instead use a keymap specific `config.h`.
+* `info.json`: The file used for setting layout for QMK Configurator. See [Configurator Support](reference_configurator_support.md) for more information.
+* `readme.md`: A brief overview of the keyboard.
+* `<keyboardName>.h`: This file is where the keyboard layout is defined against the keyboard's switch matrix.
+* `<keyboardName>.c`: This file is where you can find custom code for the keyboard.
