## Changing layouts
The layouts in [layouts.c] are generated from [squeekboard layouts] using the [unsqu33kr/unsqu33kr.py] script. To run the script use the following commands
```
$ cd unsqu33kr
$ pipenv install
$ pipenv run python unsqu33kr.py
```
Then copy the output into [layouts.c].
## Screen recording
For demonstration purposes you can record the framebuffer device, e.g. with ffmpeg:
```
$ sudo ffmpeg -f fbdev -i /dev/fb0 -r 24 -c:v libx264 -b:v 500k demo.avi
```
