+Arch does not use a repository, so binary packages are built and uploaded to GitHub
+for each release. Download the `zst` package for your architecture from the
+[releases page](https://github.com/Unpackerr/unpackerr/releases/latest)
+and install it with `pacman -U <file or url>`. Alternatively, you can build
+it yourself using the [public AUR](https://aur.archlinux.org/packages/unpackerr).
+
+If you don't want to bother figuring out which file you need, use the
+[install.sh](https://github.com/Unpackerr/unpackerr/blob/main/init/install.sh) script.
+It downloads and trusts the [GoLift GPG public key](https://golift.io/gpg) and then
+installs the binary Unpackerr package in one command, like this:
+
+```shell
+# Pick curl or wget. Run only one of these:
+curl -sL https://raw.githubusercontent.com/Unpackerr/unpackerr/main/init/install.sh | sudo bash
+wget -qO- https://raw.githubusercontent.com/Unpackerr/unpackerr/main/init/install.sh | sudo bash
+```
+
+You can run this script any time to update to the latest version. Run it weekly in cron to keep up to date automatically.

+On Linux, unpackerr runs as `user:group` `unpackerr:unpackerr`. You will need to give that

+You would do that with a command such as `sudo usermod -aG debian-transmission unpackerr`

+If you wish to change the user and/or group that unpackerr runs as you need to do exactly this, **and only this**:
+
+1. Run this command:
+   - `sudo systemctl edit unpackerr.service`
+1. The previous command opens your `$EDITOR` with a commented out version of the unpackerr service unit.
+1. Add the following content to the file editor between the comments.
+   Replace `newuser` and `newgroup` with your new values.
+   ```systemd
+   [Service]
+   User=newuser
+   Group=newgroup

+1. Run this to read the new systemd service override file:
