+Synadm
+===
+
+Simple container providing the [synadm](https://github.com/JOJ0/synadm) CLI with nicely isolated from the system.
+
+Requirements
+---
+
+Have podman installed. And in best case running [Fedora Workstation](https://getfedora.org/en/workstation/) or [Silverblue](https://silverblue.fedoraproject.org/).
+
+Installation
+---
+
+In order to install it, you just build the container yourself and get a neat little shell script installed in `~/bin/`
+
+```
+make install REGISTRY_HOST=quay.io USERNAME=shivering-isles
+synadm --help
+```

+#!/bin/bash
+
+set -x
+
+XDG_CONFIG_HOME="${XDG_CONFIG_HOME:-${HOME}/.config}"
+
+SYNADM_CONFIG_HOME="${XDG_CONFIG_HOME}/synadm"
+
+mkdir -p "$SYNADM_CONFIG_HOME"
+touch "$SYNADM_CONFIG_HOME/synadm.yaml"
+
+podman run -it --rm -v "${SYNADM_CONFIG_HOME}:/root/.config/:z" quay.io/shivering-isles/synadm:latest $@
