The "Social Media Monklet" can be inserted into the content area of a page/section to display a specific list of social icons. The "find" parameter is required in order to define which link list to use.

ex: {{social-media-monklet|find="social-links"}} 

A new list would need to be created under Content > Link Lists. Each item in the list should use the following fields: name, link and icon class. The custom icons are created by entering a custom class in the "icon class" field (ie: fa-play). 

The "Staff Monklet" can be inserted into the content area of a page to display a staff member.  This monklet requires the find_group inline parameter.

The "Gallery Monklet" can be inserted into the content area of a page to display a specific photo gallery grid.

After you insert the monklet you will use the find_gallery tag to define which gallery to use.  The name of the gallery should be in slug format, which is the gallery name in lowercase with dashes in place of spaces.

eg. using the gallery labeled "Photo Gallery 1"  {{gallery-monklet|find_gallery="photo-gallery-1"}}
