# How to add your own keymap
Folders can be named however you'd like (will be approved upon merging), or should follow the format with a preceding `_`:
_[ISO 3166-1 alpha-2 code*]_[layout variant]_[layout name/author]
\* See full list: https://en.wikipedia.org/wiki/ISO_3166-1#Officially_assigned_code_elements
and contain the following files:
* `keymap.c`
* `readme.md` *recommended*
* `config.h` *optional*, found automatically when compiling
* `Makefile` *optional*, found automatically when compling
When adding your keymap to this list, keep it organised alphabetically (select list, edit->sort lines), and use this format:
* **folder_name** description
# List of keymaps
- **default** default layout from KBDFans
- **planck** Planck default layout

# automatically to create a 32-bit value in your source code.

# This will be an integer division of F_USB below, as it is sourced by
# F_USB after it has run through any CPU prescalers. Note that this value
# does not *change* the processor frequency - it should merely be updated to
# reflect the processor speed set externally so that the code can use accurate

# differ from F_CPU if prescaling is used on the latter, and is required as the
