::: warning On NixOS you have to add `astal-auth` to `security.pam`.
::: code-group

```nix [configuration.nix]
{
  security.pam.services.astal-auth = {}
}
```

:::

2. clone repo

```sh
git clone https://github.com/aylur/astal.git
cd astal/lib/auth
```

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
```
