+
+The macOS disk image is universal and runs on both Apple silicon and Intel. Windows and Linux need the build that matches your processor.
+
+On Linux, prefer a package repository over a file. Fluxer then updates with the rest of your system.
+
+## Linux package repositories
+
+All four repositories serve stable and canary. The package is `fluxer` for stable and `fluxer-canary` for canary.
+
+### Flatpak
+
+Opening [this reference file][flatpak-ref] hands the install to your desktop software manager. Some desktops also accept `flatpak+https://pkgs.fluxer.com/flatpak/fluxer.flatpakref` pasted into the address bar.
+
+From a terminal:
+
+```sh
+flatpak install https://pkgs.fluxer.com/flatpak/fluxer.flatpakref
+```
+
+### Debian and Ubuntu
+
+```sh
+sudo install -d -m 0755 /etc/apt/keyrings
+sudo curl -fsSL -o /etc/apt/keyrings/fluxer-archive-keyring.gpg https://pkgs.fluxer.com/keys/fluxer-archive-keyring.gpg
+sudo curl -fsSL -o /etc/apt/sources.list.d/fluxer.sources https://pkgs.fluxer.com/deb/fluxer.sources
+sudo apt update && sudo apt install fluxer
+```
+
+### Fedora and RHEL
+
+```sh
+sudo curl -fsSL -o /etc/yum.repos.d/fluxer.repo https://pkgs.fluxer.com/rpm/fluxer.repo
+sudo dnf install fluxer
+```
+
+RHEL, Rocky, Alma and CentOS Stream need `sudo dnf install epel-release` first, because the base repositories do not ship `libXScrnSaver`. Fedora does not need this.
+
+### Arch Linux
+
+The repository is signed, so pacman needs the key in its own keyring once:
+
+```sh
+sudo pacman-key --init
+curl -fsSL -o /tmp/fluxer-archive-keyring.asc https://pkgs.fluxer.com/keys/fluxer-archive-keyring.asc
+sudo pacman-key --add /tmp/fluxer-archive-keyring.asc
+sudo pacman-key --lsign-key 09D01339EE128925F75E675C855C5BDE34D205D2
+```
+
+`--lsign-key` is the step that makes pacman trust the key. Then add the repository:
+
+```sh
+sudo tee -a /etc/pacman.conf >/dev/null <<'REPO'
+
+[fluxer]
+SigLevel = Required TrustedOnly
+Server = https://pkgs.fluxer.com/arch/$repo/os/$arch
+REPO
+sudo pacman -Syu fluxer
+```
+
+Write `$repo` and `$arch` literally. Both are pacman variables, not shell ones, which is why the heredoc above is quoted.
+
+Full setup notes, including the canary channel, live in the [Linux repositories documentation][docs-linux].
