-{% capture headingsWorkspace %}
-  {% comment %}
-    Version 1.0.0
-      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
-
-    Output:
-      The original HTML with the addition of anchors inside of all of the h1-h6 headings.
