+# Contribution Analytics (EE only)
+
+_**Note:** This feature was introduced in GitLab EE 8.3._
+
+With contribution analytics you can have an overview for the activity of
+issues, merge requests and push events of your organization and its members.
+
+The analytics page is located at **Group > Contribution Analytics**
+under the URL `/groups/<groupname>/analytics`.
+
+The time period on which the analytics depend on, is spanned in three sections:
+last week, last month and last three months. You can choose which one to
+display by using the dropdown calendar menu in the upper right corner.

+
+There are three main bar graphs that are deducted from the number of
+contributions per group member. These contributions include push events, merge
+requests and closed issues. Hovering on each bar you can see the number of
+events for a specific member.
+
+Below is an example of the push events of the
+[gitlab-org][https://gitlab.com/groups/gitlab-org] group.

+
+Apart from the bar graphs you can also see the contributions per group member
+which are depicted in a table that can be sorted by:
+
+* Member name
+* Number of pushed events
+* Number of opened issues
+* Number of closed issues
+* Number of opened MRs
+* Number of accepted MRs
+* Number of total contributions
