+
+The Gitter panel shows information about the messages sent in a Gitter room over time. 
+The references included in these messages are used to highlight mentioned users and links 
+to issue trackers (e.g., GitHub and GitLab) and other resources. 
+
+Each user in a room is uniquely identified by a username and a user-id. This
+information is used to identify the most active and mentioned users.
+Similarly, the links shared are identified as github issues or pull requests
+or categorized into URL hostnames if they belong to other sources (e.g., StackOverflow, Twitter).
+
+Weekly, hourly and daily activity of the room is put into perspective by
+widgets displaying the number of messages sent or unique users active in
+the for selected time range. 
+
+* **Top users chart** shows the people most active in a room (messages sent), for the selected time range.
+* **Top mentioned URLs** gives an overview of the most common websites being linked in the room.
+* **Weekly active users** displays the number of unique users active in the room per week.
+* **Daily message count** displays the number of messages sent daily.
+* **Users reading messages daily** shows the average number of users reading messages daily.
+* **Top mentioned users/pull requests/issues** shows the respective most mentioned field in the messages over the selected time zone.
+* **Messages sent per hour** shows the most active hours, when the most messages are sent in a day.
