-
-As a benefit of having the [usage ping active](settings/usage_statistics.md),
-GitLab lets you analyze the users' activities of your GitLab installation.
-Under `/admin/cohorts`, when the usage ping is active, GitLab will show the
-monthly cohorts of new users and their activities over time.
-
-## Overview
-
-How do we read the user cohorts table? Let's take an example with the following
-user cohorts.
-
-![User cohort example](img/cohorts.png)
-
-For the cohort of June 2016, 163 users have been added on this server and have
-been active since this month. One month later, in July 2016, out of
-these 163 users, 155 users (or 95% of the June cohort) are still active. Two
-months later, 139 users (or 85%) are still active. 9 months later, we can see
-that only 6% of this cohort are still active.
-
-The Inactive users column shows the number of users who have been added during
-the month, but who have never actually had any activity in the instance.
-
-How do we measure the activity of users? GitLab considers a user active if:
-
-* the user signs in
-* the user has Git activity (whether push or pull).
-
-## Setup
-
-1. [Activate the usage ping](settings/usage_statistics.md)
-2. Go to `/admin/cohorts` to see the user cohorts of the server

+Instance statistics gives users or admins access to instance-wide analytics.
+They are accessible to all users by default (GitLab admins can restrict its
+visibility in the [admin area](../admin_area/settings/usage_statistics.md)),
+and can be accessed via the top bar.
+
+![Instance Statistics button](img/instance_statistics_button.png)
+
+For the statistics to show up, [usage ping must be enabled](../admin_area/settings/usage_statistics.md#usage-ping)
+by an admin in the admin settings area.
+
+There are two kinds of statistics:
+
+- [Conversational Development (ConvDev) Index](convdev.md): Provides an overview of your entire instance's feature usage.
+- [User Cohorts](user_cohorts.md): Display the monthly cohorts of new users and their activities over time.
