+Site-wide categories
+--------------------
+
+NOTES FOR PROGRAMMERS:
+
+If you're not a programmer, don't worry! All the main Elgg tools
+are already adapted to use categories, and a growing number of
+third party Elgg tools use it too.
+
+
+This plugin uses views and events hooks to allow you to easily add
+site-wide categories across Elgg tools.
+
+This is a two-line addition to any plugin.
+
+In your edit/create form:
+
+	echo elgg_view('categories', $vars);
+
+In your object view:
+
+	echo elgg_view('categories/view', $vars);
+	
+Note that in both cases, $vars['entity'] MUST be populated with
+the entity the categories apply to, if it exists. (i.e., there's
+no need for this on a create form.)
