PHP requirement not documented

[theCapypara]

It seems that baler needs a PHP executable. This is not documented. Of course if you work with Magento you usually also have PHP installed, but I was building a Docker image for baler and didn't realize that PHP was also directly required for executing baler.

It would be great, if the documentation included that information.

Also why does baler need a PHP executable...?
