#### Adding the Repository
Import and locally sign the packager's GPG key. This can be skipped if the
signature checking is disabled when adding the repo.
Install packages with a list of mirrors and GPG keys
```
$ sudo pacman-key --recv-keys 697C63013E65270255EBC2608744DC1EB26B5A9A
$ sudo pacman-key --lsign-key 697C63013E65270255EBC2608744DC1EB26B5A9A
sudo pacman -U 'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-keyring-3-1-any.pkg.tar.zst' 'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-mirrorlist-18-1-any.pkg.tar.zst'
```
Add the following custom repository section to `/etc/pacman.conf`.
```
[scx]
Server = https://github.com/sched-ext/scx-packaging-arch/releases/download/repo
# cachyos repos
[cachyos]
Include = /etc/pacman.d/cachyos-mirrorlist
```
You can also import the gpg key manually. This can be skipped if the
signature checking is disabled when adding the repo.
```
$ sudo pacman-key --recv-keys F3B607488DB35A47 --keyserver keyserver.ubuntu.com
$ sudo pacman-key --lsign-key F3B607488DB35A47
```
If you haven't imported the GPG key, append the following line.

#### Installing the Kernel and Schedulers
```
$ sudo pacman -Sy scx/linux scx/libbpf scx/scx-scheds
$ sudo pacman -Sy cachyos/linux-sched-ext cachyos/linux-sched-ext-headers cachyos/scx-scheds
```
Note that the above replaces the default kernel and libbpf packages. The
latter won't be unnecessary once libbpf is updated to >=1.3.0 in the Arch
repository. After a reboot, the scheduler binaries `/usr/bin/scx_*` should
be usable.
#### Setting Up Dev Environment
In addition to the packages from the previous step, install the following.
```
$ sudo pacman -Sy scx/linux-headers scx/clang-github-bin meson cargo bpf pahole
$ sudo pacman -Sy cachyos/clang-github-bin meson cargo bpf pahole
```
`clang-github-bin` is necessary because the recommended `clang` version is
