+        "...like all things liquid - where there's a will, and ~36 hours to spare, there's usually a/some way" ~jaybe
+
+        Usage:
+            {% include toc.html html=content sanitize=true class="inline_toc" id="my_toc" h_min=2 h_max=3 %}
+
+        Parameters:
+            * html         (string) - the HTML of compiled markdown generated by kramdown in Jekyll
+
+        Optional Parameters:
+            * sanitize     (bool)   : false  - when set to true, the headers will be stripped of any HTML in the TOC
+            * class        (string) :   ''   - a CSS class assigned to the TOC
+            * id           (string) :   ''   - an ID to assigned to the TOC
+            * h_min        (int)    :   1    - the minimum TOC header level to use; any header lower than this value will be ignored
+            * h_max        (int)    :   6    - the maximum TOC header level to use; any header greater than this value will be ignored
+            * ordered      (bool)   : false  - when set to true, an ordered list will be outputted instead of an unordered list
+            * item_class   (string) :   ''   - add custom class(es) for each list item; has support for '%level%' placeholder, which is the current heading level
+            * baseurl      (string) :   ''   - add a base url to the TOC links for when your TOC is on another page than the actual content
+            * anchor_class (string) :   ''   - add custom class(es) for each anchor element
+
+        Output:
+            An ordered or unordered list representing the table of contents of a markdown block. This snippet will only
+            generate the table of contents and will NOT output the markdown given to it
