## Compilation
The `desktop` and `sound` features require additional system dependencies:
| Feature | Dependency | PKG Name on Debian based Distributions |
|-----------|------------|----------------------------------------|
| `desktop` | dbus | `libdbus-1-dev` |
| `sound` | alsa | `libasound2-dev` |
If you want to compile without these features, you will not have notifications
and sound alerts for countdown mode. (Use `cargo build -r --no-default-features`)
## Acknoledgements
The included alarm sound is from [freesound.org](https://freesound.org):
-> ["effect_notify.wav" by ricemaster (CC-0)](https://freesound.org/people/ricemaster/sounds/278142/)
