 Introduction
 ------------
 
+A plugin for the Footnotes module (https://www.drupal.org/project/footnotes) 
+that lets a user insert references created or importeed using the Bibliography 
+and Citation project (https://www.drupal.org/project/bibcite).
+
 Provides a CKEditor plugin that lets a user select from a list of citations which
-appear in a formatted list at the bottom of the text that contains endnotes
-and references.
+appear in a formatted at the bottom of the text area that contains the footnote.
 
 Installation
 ------------
 
-### Works Cited field
-
-1. Go to Administration > Structure > Content Types and edit the type that will include Reference Footnotes
-2. In the Manage Fields tab, press Add Field.
-3. In "Re-use an existing field" select "Entity reference: field_bibcite_fn_works_cited".
-4. Enter an appropriate label and press 'Save and continue'.
-5. On the next page select all the items in "Reference type" that should be available to choose from as footnotes.
-6. Customize the field under "Manage form display" and "Manage display", typically you'll want to 
-   place the Works Cited field directly under the Body field. See below for configuring with 
-   Inline Entity Form.
-7. In "Manage display", select "Rendered entity" in the Format drop-down for the Works Cited field.
-8. Press the Settings icon and under "View mode" choose "Citation" - a new view mode created 
-   by this module.
-
-#### Inline Enity Form
-
-It's recommended to also install [Inline Entity Form][1] which allowes a user to
-create new references directly in the node edit form.
-
-1. In "Entity Form Display", select ''Inline Entity Form - complex".
-2. Press the settings button in the rightmost column.
-3. Enabling  "Allow users to add new reference entities" and
-   "Allow users to add existing reference entities" is recommended. 
-
-[1]: https://www.drupal.org/project/inline_entity_form
-
-### CKEditor filter and toolbar button
-
-1. Enable the module.
-2. Go to Administration > Configuration > Content authoring > Text formats and editors.
- 3. Edit the text format you want to add Reference Footnotes to
-4. Enable the Reference Footnotes Filter
-5. Drag the Reference Footnotes button into the active buttons toolbar.
-6. Configure the options for the Reference Footnotes Filter.
-
-If the 'Allowed HTML tags' filter is enabled add these HTML tags to the allowed list:
+Install and set up the Footnotes module as per its installation instructions, including
+enabling and configuring the Footnotes text filter. If the 'Allowed HTML tags' filter is enabled
+you will need to add the following HTML tags for the reference footnotes to display properly.:
 
 ```html
-    <a class href id> <div class id> <span class id> <ol class id type> 
-	<sup> <li class id>
+    <a class href id> <div class id> <span class id> <ul class id type> 
+	<ol class id start type> <sup> <li class id>
 ```
 
-Use
----
-
-See the documentation for [Bibliography and Citation - Import][2] module for how to
-add citations exported from a citation management system like RefWorks or EndNote.
+Configuration
+-------------
 
-[2]: https://www.drupal.org/project/bibcite
+Drag the Reference Footnotes button into the active set of buttons in the text format
+you want to use References in and save the settings.
 
-### Adding a Works Cited item
-
-If Inline Entity Form is enabled, an author can create new citations or add references to 
-previously-imported or created references directly with the 'Add new reference' and 
-'Add existing reference' buttons.
-
-With Inline Entity Form, newly-added citations are immediately selectable in the 
-Reference Footnotes dialog.
-
-If not using the inline entity form, you can select previously imported or created references 
-
-When you edit the node again, and you click on the Reference Footnote editor toolbar button,
-a list of citations will be available to choose from.
-
-### Citation Formatting
-
-The Works Cited field will use the Default style selected in the 
-Bibliography & Citation administration pages at Administration > Configuration > 
-Bibliography & Citation > Settings in the Processing tab under Processor.'
+You will then need to create or import one or more references using the Bibliography &
+Citations project. Those will then appear in a select list when you are editing a text area
+and click on the Reference Footnote button.
