@ -135,6 +135,28 @@ Creates a keymap.c from a QMK Configurator export.
qmk json-keymap [-o OUTPUT] filename
```
## `qmk kle2json`
This command allows you to convert from raw KLE data to QMK Configurator JSON. It accepts either an absolute file path, or a file name in the current directory. By default it will not overwrite `info.json` if it is already present. Use the `-f` or `--force` flag to overwrite.
**Usage**:
```
qmk kle2json [-f] <filename>
```
**Examples**:
```
$ qmk kle2json kle.txt
☒ File info.json already exists, use -f or --force to overwrite.
```
```
$ qmk kle2json -f kle.txt -f
Ψ Wrote out to info.json
```
## `qmk list-keyboards`
This command lists all the keyboards currently defined in `qmk_firmware`
