Usage:

use My\Namespace\TemplateProcessor;

$templatePath = '...';
$outputPath = '...';
$search = 'replaceMe';
$markdown = "### Bulleted lists are good for:\n\n* Listing things\n* Organizing things that do not have an order\n* Keeping things in lists";

$template = new TemplateProcessor($templatePath);
$template->replaceMarkdown($search, $markdown);
$template->saveAs($outputPath);

Note that the <w:AltChunk /> element follows the same placement rules as <w:p> elements. Just placing the placeholder string ${replaceMe} in the document may not be sufficient, you may need to modify the main document part (document.xml) inside of the DOCX archive of your template so that you guarantee it is not inside of a text run or similar elemnts (e.g. <w:r> or <w:Pr>). It most likely needs to be placed as a sibling of the nearest paragraph element.
