 Available options:
+
 - `image`: The image shown _required_
 - `caption`: A caption to explain the image
 - `position`: The position of the image; `left`, `right` or `center`

 This include has no options. This include will add a block of javascript to the page and javascript reference in order for the search field to work correctly.
 
 ### `site-before-start.html` & `site-before-end.html`
+
 Optional html includes for adding scripts, css, js or any embed code you wish to add to every page without the need to overwrite the entire `default.html` template.
 
 **Example usage:** These are different to other includes as they are designed to be overwritten. If you create a `site-before-start.html` file in the `_includes/` the contents of the file will be included immediately before the closing `</head>` tag. If you create a `site-before-end.html` file the contents of the file will be included immediately before the closing `</body>` tag.
