 # Inline HTML Galley plugin for PKP
 
-This plugin provides inline display of article galleys for PKP Open Journal Systems, replacing the default HTML Article Galley plugin's use of an iframe to deliver the HTML Galleys.  Also consider the [Alternate HTML Galley plugin](https://github.com/ajnyga/embedHtmlArticleGalley).  This plugin will present the galley content within your website's theme.  The Alternate HTML Galley plugin will present the galley in the same manner as the HTML Article Galley plugin (with just a simple header), but without requiring an iframe.

 Login as a Journal Manger and navigate to the Journal for which you wish to use inline display of HTML Galleys.  Enable the plugin via Login -> Settings -> Website -> Plugins -> Inline HTML Galley -> Enable.
 
-There are no settings to configure for this plugin.  Once enabled, the view of an HTML Galley will extract the HTML `body` from the Galley and will place it inline in the Galley view.  You will need to replicate any CSS or Javascript directives used in the `head` of the Galley in your website configuration.  (Hint: see the Custom Headers plugin.)

You will need to replicate any CSS or Javascript directives used in the `head` of the Galley in your website configuration.  (Hint: see the Custom Headers plugin.)
 
-The template will provide a link to the "download" handler for the galley above the extracted text of the Galley.  The plugin also provides a sidebar block to link to the download, which may be enabled and positioned via the Website Settings.
+The Settings Form allows you to target another arbitrary HTML element from which to extract the HTML, via xpath.  For example, since you likely have the article's title in an `h1` in the `body`, and Bootstrap3 will render the article title independently, you might want to target a content `div` within the body.

+The plugin provides article metadata as sidebar blocks, which may be enabled and positioned via the Website Settings.
