+# Managing Recommendations
+
+The Recommendations Hub allows you granular control over which collections appear on your home screen, the home screen of other users, and the Recommended tab of any given library.
+
+You can use this to disable Plex's default recommendations (such as "Recently Added in Movies") and replace them with any of your favorite Kometa Collections.
+
+
+## Getting Started
+
+The Recommendations tab is accessed by going to `Settings > Server > Manage > Libraries` within Plex. You can then press the "Manage Recommendations" button against any of your libraries to view the current configuration.

+
+For the purpose of this guide we will disable **all** enabled recommendations.

+
+In order for a Kometa collection to appear as a Row in the Manage Recommendations section, it must have one of the `visible_home`/`visible_shared`/`visible_library` attributes set to `true`, this can be done in your Collection definition or via a template variable for Defaults files. You can also set these visibility options within the Plex UI, you can read [Plex's guidance](https://support.plex.tv/articles/manage-recommendations/) on how to do this. 
+
+Here is an example Collection definition setting all three `visible_*` attributes:
+
+```yaml
+collections:
+  Test:
+    plex_all: true
+    visible_home: true
+    visible_shared: true
+    visible_library: true
+```
+
+And an example Defaults file setting the same attributes:
+```yaml
+libraries:
+  Movie Recommendations:
+    collection_files:
+      - default: imdb
+        template_variables:
+          visible_home: true
+          visible_shared: true
+          visible_library: true
+```
+
+The results are:

+
+And if I visit my Plex homepage:
+
+![hub4.png](images/hub4.png)
+
+Collections will be added in the order that Kometa processes them, but you can reorganize them by drag-and-dropping each Row using the tree-line icon.
