+Site pages - Quickly generate static pages and customize the front page, CSS, and
+HTML metatags.
+
+CONTENTS:
+	1.  Overview
+	2.  Using Front Page Keywords
+		2.1  Built-in keywords
+		2.2  Entities
+		2.3  Views
+	3.  Custom Front Page Keywords
+	4.  Hints and Quirks
+
+
+1.  OVERVIEW
+
+	Site Pages provides a simple way to create static content for About, Terms,
+	and Privacy pages, and also allows simple modifications of the logged in
+	and logged out views, as well as CSS and meta description and tags for SEO.
+
+	The biggest feature of Site Pages is its support for an extensible keyword
+	system that allows end-users to quickly add elements to the front page of
+	their site. 
+
+
+2.  USING FRONT PAGE KEYWORDS
+
+	Keywords are specially formatted strings that can be used on the logged in
+	and logged out front pages to include lists of objects, views, or plugin-
+	supplied content.  All keywords are surrounded by two brackets: 
+	[[keyword]].  Some keywords, like views and entity lists, take optional 
+	parameters.
+
+	When editing the front pages, a list of available keywords appears in the 
+	sidebar.
+
+
+2.1  BUILT IN KEYWORDS
+
+	Site Pages includes a few built-in keywords to get you started:
+		[[login_box]] - This keyword is required on the logged out page to
+						Allow users to log into your site.
+
+		[[site_stats]] - Shows the total members in your site, the currently
+						active members, and other fun stuff.
+
+
+2.2  Entities
+
+	You can generate a list of entities by using the [[entity]] keyword.  This
+	keyword takes similar arguments to the elgg_get_entities() function.  See
+	documentation in that function for a complete list.
+
+	Additional / changed parameters supported by keywords:
+	* owner: The username owner. (You can still use owner_guid)
+
+	Example: To generate a list of all blog posts by the user named 'admin':
+		[[entities: type=object, subtype=blog, owner=admin]]
+
+	Example: To show newest group created:
+		[[entities: type=object, subtype=group, limit=1]]
+
+
+2.1 Views
+
+	Keywords support outputting arbitrary views with the [[view]] keyword and
+	supports passing arguments as name=value pairs.
+
+	Example: Output a text input field with a default value:
+		[[view: input/text, value=This is a test!]]
+
+	NB: Do NOT quote the name or values when passing them.  Also, as of 1.8
+	using commas or = in the name or value is unsupported.
+
+
+3.0  CUSTOM FRONT PAGE KEYWORDS
+
+	Plugins can add their own keywords by replying to the 'get_keywords' hook
+	of type 'sitepages.'  Each keyword must be bound to a valid view.  Almost 
+	all functionality in custom keywords could be implemented using the 'view' 
+	keyword, but custom keywords provide a simple way for non-techy users to 
+	include ready-made views without the fuss of knowing what they're doing.
+
+	The below example creates the 'my_plugin_keyword' keyword that displays the
+	view at 'my_plugin/keyword_view.'
+
+	This is exactly the same as saying [[view: my_plugin/keyword_view]] but
+	much simpler for the user.
+
+	Example:
+		register_plugin_hook('get_keywords', 'sitepages', 'my_plugin_keywords');
+
+		function my_plugin_keywords($hook, $type, $value, $params) {
+			$value['my_plugin_keyword'] = array(
+				'view' => 'my_plugin/keyword_view',
+				'description' => 'Provides the awesome My Plugin keyword'
+			);
+
+			return $value;
+		}
+
+	NB: No variables are passed to the view when using custom keywords.
+
+
+4.  HINTS AND QUIRKS
+
+	* A custom keyword is more complicated to implement, but simpler for the
+	end user.
+
+	* The view and entity keywords have limited support for passing arguments, 
+	but the arguments cannot contain '=' or ','.  If you need complicated
+	arguments, it's best to create a custom keyword with a custom view.
