# Example: Custom Phase Script

This is my (lightly edited) personal Custom Phase script that I used to use. I am now using a <a href="Plugins.md">Plugin</a>, which you can see <a href="Example-Plugin.md">here</a> for comparison and contrast.
```sh
#!/bin/bash
# My sdm customizations
#
function loadparams() {
    source $SDMPT/etc/sdm/sdm-readparams
}
#
# $1 is the phase: "0", "1", or "post-install"
#
phase=$1
pfx="$(basename $0)"
if [ "$phase" == "0" ]
loadparams
then
    #
    # In Phase 0 all references to directories in the image
    # must be preceded by $SDMPT. References not preceded
    # by $SDMPT refer to the system on which sdm is running.
    # Hence easy to copy additional files into the image.
    #
