-alias butane='podman run --rm --interactive       \

               quay.io/coreos/butane:release'
 ```
 
+Alternatively you may also create a wrapper script at `~/.local/bin/butane`:

+     --volume "${PWD}":/pwd --workdir /pwd \
+     quay.io/coreos/butane:release         \
+     "${@}"
+```
+
+Make sure that `~/.local/bin` is in your `$PATH`, or choose another path like `/usr/local/bin`.
