+## Introduction

+The livechat plugin includes a Moderator Notes Application: you can write some notes, that could be associated to chat participants.
+Every room's admins have access to these notes, so they can edit them collaboratively.
+
+You can for example use this Application to:
+
+* share some notes between moderators
+* take notes about participants that were kicked or caused troubles
+* ...
+
+## Using the Moderator Notes Application

+
+You can create a note associated to a participant in several ways:
+
+* using the "{{% livechat_label moderator_note_create_for_participant %}}" action in the dropdown menu besides chat messages
+
+When a note is associated to a participant, you will see their nickname and avatar on the top of the note.
+
+#### Notes filtering
+
+You can filter notes to find all notes related to a given participant in several ways:
+
+* click on the "{{% livechat_label moderator_note_search_for_participant %}}" button that is available on notes to find all notes related to the same participant
+* click on the "{{% livechat_label moderator_note_search_for_participant %}}" button in the dropdown menu besides chat messages
+
+You can remove the filter by clicking on the close button.
+
+![Moderator Notes Application - filtering](/peertube-plugin-livechat/images/moderation_notes_filters.png?classes=shadow,border&height=200px)
+
+When you filters notes on a participant, there are several informations that are shown at the right of the participant nickname:
+
+* if the current nickname is different than the nickname when you created the note, the original nickname will be shown
+* you will see the [JID (Jabber ID)](https://xmpp.org/extensions/xep-0029.html) of the participant
+* you will also see the [occupant-id](https://xmpp.org/extensions/xep-0421.html) of the participant
+
+The search result will also include all notes related to participants who had the same nickname.
+So you can also take note for anonymous users (who don't have any consistent JID or occupant-id).
+You can differenciate them by comparing JID and occupant-id.
+
+#### Sorting notes
+
+You can sort notes simply using drag & drop.
