+    This template pulls in the file from `source` in the front matter.
+
+    It detects if the script starts with front matter (delimited by `---`) by splitting and looking for the delimiter at the start of the file.
+    If the delimter is detected at the top of the file, it skips the the 3rd (zero based: 2) element and iterates over the remain sections.
+    If there delmiter is not detected (no front matter) it swallows the the whole file and markdownify's it.
