+ Version 1.0.3
+ https://github.com/allejo/jekyll-anchor-headings
+
+ "Be the pull request you wish to see in the world." ~Ben Balter
+
+ Usage:
+ {% include anchor_headings.html html=content %}
+
+ Parameters:
+ * html (string) - the HTML of compiled markdown generated by kramdown in Jekyll
+
+ Optional Parameters:
+ * beforeHeading (bool) : false - Set to true if the anchor should be placed _before_ the heading's content
+ * anchorBody (string) : '' - The content that will be placed inside the anchor; the `%heading%` placeholder is available
+ * anchorClass (string) : '' - The class(es) that will be used for each anchor. Separate multiple classes with a space
+ * anchorTitle (string) : '' - The `title` attribute that will be used for anchors
+ * h_min (int) : 1 - The minimum header level to build an anchor for; any header lower than this value will be ignored
+ * h_max (int) : 6 - The maximum header level to build an anchor for; any header greater than this value will be ignored
+ * bodyPrefix (string) : '' - Anything that should be inserted inside of the heading tag _before_ its anchor and content
+ * bodySuffix (string) : '' - Anything that should be inserted inside of the heading tag _after_ its anchor and content
+
+ Output:
+ The original HTML with the addition of anchors inside of all of the h1-h6 headings.
