 To build with the default keymap, simply run `make`.
 
 ### Other Keymaps
-Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create a file in the keymaps folder named `<name>.c` and see keymap document (you can find in top README.md) and existent keymap files.

 To build the firmware binary hex file with a keymap just do `make` with `KEYMAP` option like:
