+## After update hooks
+There are two actions that can be used after a post is updated and passes a single post ID. Please make sure you see the subtle difference in these two hooks.
+
+The first is run after each related post is updated
+```
+add_action('acf/post2post/relationship_updated', 'my_post_updated_action');
+function my_post_updated_action($post_id) {
+  // $post_id == the post ID that was updated
+  // do something after the related post is updated
+}
+```
+
+The second is run after all posts are updated and passes an array of post IDs.
+```
+add_action('acf/post2post/relationships_updated', 'my_post_updated_action');
+function my_post_updated_action($posts) {
+  // $posts == and array of post IDs that were updated
+	// do something to all posts after update
+	foreach ($posts as $post_id) {
+	  // do something to post
+	}
+}
+```
+
 ## So why do this?
 
-I did not actually create this plugin to make it easier on the person that's managing a site, although that is
-an added side benifit. The main reason for implementing some way to make relationship and post object fields
-biderectional is that doing reverse relationship queries for ACF is a huge PITA. I completely understand why this is
-not built into ACF. If it was built in then Elliot would need to deal with relationship fields in repeaters and
-flex fields and nested repeaters. And then there is the problem of relationships with different post types and fields
-with different names. It would be a deep dark rabbit hole from which I don't think he'd return. There are too many
-parameters. On the other hand, filters and actions can be created with a finite number of options to do the work that's
-needed.

 #### Automatic Updates
 Github updater support has been removed. This plugin has been published to WordPress.Org here
 https://wordpress.org/plugins/post-2-post-for-acf/. If you are having problems updating please
 try installing from there. 
 
-#### Remove Nag
-You may notice that I've started adding a little nag to my plugins. It's just a box on some pages that lists my
-plugins that you're using with a request to consider making a donation for using them. If you want to disable them
-add the following filter to your functions.php file.
-```
-add_filter('remove_hube2_nag', '__return_true');
-```
