+### `config.h`
+
+All projects need to have a `config.h` file to set things like the processor type, bootloader, USB VID/PID, and other default settings. In general you should use this file to set reasonable defaults for your keyboard that will always work.
+
+### `rules.mk`
+
+The prescence of this file means this folder is a keyboard target, and can be used in make commands. This is where you setup the build environment for your keyboard and configure the default set of features.
+
+### `<keyboard_name.c>`
+
+This is where you will write custom code for your keyboard. Typically you will write code to initialize and interface with the hardware in your keyboard. If your keyboard consists of only a key matrix with no LEDs, speakers, or other auxillary hardware this file can be blank.
+
+The following functions are typically defined in this file:
+
+* `void matrix_init_kb(void)`
+* `void matrix_scan_kb(void)`
+* `bool process_record_kb(uint16_t keycode, keyrecord_t *record)`
+* `void led_set_kb(uint8_t usb_led)`
+
+### `<keyboard_name.h>`
+
+This file is used to define the matrix for your keyboard. You should define at least one CPP macro named `LAYOUT` which translates an array into a matrix representing your switch matrix. If it's possible to build your keyboard with multiple layouts you may define additional macros.
+
+When defining multiple layouts you should have a base layout, named `LAYOUT`, that supports all possible switch positions on your matrix, even if that layout is impossible to build physically. This is the macro you should use in your `default` keymap. You should then have additional keymaps named `default-<layout>` that use your other layout macros. This will make it easier for people to use the layouts you define.
+
+Layout macro names are entirely lowercase, except for the word `LAYOUT` at the front.
+
+As an example, if you have a 60% PCB that supports ANSI and ISO you might define the following layouts and keymaps:
+
+| Layout Name | Keymap Name | Description |
+|-------------|-------------|-------------|
+| LAYOUT | default | A keymap that supports both ISO and ANSI |
+| LAYOUT_ansi | default-ansi | An ANSI layout |
+| LAYOUT_iso | default-iso | An ISO layout |
