```vala [<i class="devicon-vala-plain"></i> Vala]
// Not yet documented
```
:::
## Installation
1. install dependencies
Note that it requires [libcava](https://github.com/LukashonakV/cava), a fork of cava, which provides cava as a shared library.
:::code-group
```sh [<i class="devicon-archlinux-plain"></i> Arch]
sudo pacman -Syu meson vala gobject-introspection
paru -S libcava
```
```sh [<i class="devicon-fedora-plain"></i> Fedora]
# Not yet documented
```
```sh [<i class="devicon-ubuntu-plain"></i> Ubuntu]
# Not yet documented
```
:::
2. clone repo
```sh
git clone https://github.com/aylur/astal.git
cd astal/lib/cava
```
3. install
```sh
meson setup build
meson install -C build
```
:::tip
Most distros recommend manual installs in `/usr/local`,
which is what `meson` defaults to. If you want to install to `/usr`
instead which most package managers do, set the `prefix` option:
```sh
meson setup --prefix /usr build
```
