+# Contribution Analytics **[STARTER]**
+
+>**Note:**
+Introduced in [GitLab Starter][ee] 8.3.
+
+Track your team members' activity across your organization.
+
+## Overview
+
+With Contribution Analytics you can get an overview of 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`.
+
+## Use cases
+
+- Analyze your team's contributions over a period of time and offer a bonus for the top contributors
+- Identify opportunities for improvement with group members who may benefit from additional support 
+
+## Using Contribution Analytics
+
+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.
+
+![Contribution analytics bar graphs](img/group_stats_graph.png)
+
+## Changing the period time
+
+There are three periods you can choose from, 'Last week', 'Last month' and
+'Last three months'. The default is 'Last week'.
+
+You can choose which period to display by using the dropdown calendar menu in
+the upper right corner.
+
+![Contribution analytics choose period](img/group_stats_cal.png)
+
+## Sorting by different factors
+
+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

+# Epics **[ULTIMATE]**
+
+> Introduced in [GitLab Ultimate][ee] 10.2.
+
+Epics let you manage your portfolio of projects more efficiently and with less
+effort by tracking groups of issues that share a theme, across projects and
+milestones.
+
+![epics list view](img/epics_list_view.png)
+
+## Use cases
+
+- Suppose your team is working on a large feature that involves multiple discussions throughout different issues created in distinct projects within a [Group](../index.md). With Epics, you can track all the related activities that together contribute to that single feature.
+- Track when the work for the group of issues is targeted to begin, and when it is targeted to end.
+- Discuss and collaborate on feature ideas and scope at a high-level.
+
+## Creating an epic
+
+A paginated list of epics is available in each group from where you can create
+a new epic. The list of epics includes also epics from all subgroups of the
+selected group. From your group page:
+
+1. Go to **Epics**
+1. Click the **New epic** button at the top right
+1. Enter a descriptive title and hit **Create epic**
+
+Once created, you will be taken to the view for that newly-created epic where
+you can change its title, description, start date, and due date.
+
+![epic view](img/epic_view.png)
+
+## Adding an issue to an epic
+
+An epic contains a list of issues and an issue can be associated with at most
+one epic. When on an epic, you can add its associated issues:
+
+1. Click the plus icon (<kbd>+</kbd>) under the epic description.
+1. Paste the link of the issue (you can hit <kbd>Spacebar</kbd> to add more than
+   one issues at a time).
+1. Click **Add**.
+
+Any issue belonging to a project in the epic's group or any of the epic's
+subgroups are eligible to be added. To remove an issue from an epic, click
+on the <kbd>x</kbd> button in the epic's issue list.
+
+NOTE: **Note:**
+When you add an issue or an epic to an epic that's already associated with another epic,
+the issue or the epic is automatically removed from the previous epic.
+
+## Multi-level child epics
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/8333) in GitLab Ultimate 11.7.
+
+Much like adding issues to an epic, an epic can have multiple child epics with
+the maximum depth being 5. To add a child epic:
+
+1. Click the plus icon (<kbd>+</kbd>) under the epic description.
+1. Paste the link of the epic.
+1. Click **Add**.
+
+Any epic that belongs to a group or subgroup of the parent epic's group is
+eligible to be added. To remove a child epic from a parent epic,
+click on the <kbd>x</kbd> button in the parent epic's epic list.
+
+## Start date and due date
+
+For each of the dates in the sidebar of an epic, you can choose to either:
+
+- Enter a fixed value.
+- Inherit a dynamic value called "From milestones".
+
+If you select "From milestones" for the start date, GitLab will automatically set the
+date to be earliest start date across all milestones that are currently assigned
+to the issues that are attached to the epic. Similarly, if you select "From milestones"
+for the due date, GitLab will set it to be the latest due date across all
+milestones that are currently assigned to those issues.
+
+These are dynamic dates in that if milestones are re-assigned to the issues, if the
+milestone dates change, or if issues are added or removed from the epic, then
+the re-calculation will happen immediately to set a new dynamic date.
+
+## Roadmap in epics
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/7327) in [GitLab Ultimate](https://about.gitlab.com/pricing) 11.10.
+
+If your epic contains one or more [child epics](#multi-level-child-epics) which
+have a [start or due date](#start-date-and-due-date), then you can see a
+[roadmap](../roadmap/index.md) view of the child epics under the parent epic itself.
+
+![Child epics roadmap](img/child_epics_roadmap.png)
+
+## Reordering issues and child epics
+
+Drag and drop to reorder issues and child epics. New issues and child epics added to an epic appear at the top of the list.
+
+## Deleting an epic
+
+NOTE: **Note:**
+To delete an epic, you need to be an [Owner][permissions] of a group/subgroup.
+
+When inside a single epic view, click the **Delete** button to delete the epic.
+A modal will pop-up to confirm your action.
+
+Deleting an epic releases all existing issues from their associated epic in the
+system.
+
+## Closing and reopening epics
+
+### Using buttons
+
+Whenever you decide that there is no longer need for that epic,
+close the epic using the close button:
+
+![close epic - button](img/button_close_epic.png)
+
+You can always reopen it using the reopen button.
+
+![reopen epic - button](img/button_reopen_epic.png)
+
+### Using quick actions
+
+You can close or reopen an epic using [Quick actions](../../project/quick_actions.md)
+
+## Navigating to an epic from an issue
+
+If an issue belongs to an epic, you can navigate to the containing epic with the
+link in the issue sidebar.
+
+![containing epic](img/containing_epic.png)
+
+## Promoting an issue to an epic
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/3777) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.6.
+
+If you have [permissions](../../permissions.md) to close an issue and create an
+epic in the parent group, you can promote an issue to an epic with the `/promote`
+[quick action](../../project/quick_actions.md#quick-actions-for-epics-ultimate).
+Only issues from projects that are in groups can be promoted.
+
+When the quick action is executed:
+
+- An epic is created in the same group as the project of the issue.
+- Subscribers of the issue are notified that the epic was created.
+
+The following issue metadata will be copied to the epic:
+
+- Title, description, activity/comment thread.
+- Upvotes/downvotes.
+- Participants.
+- Group labels that the issue already has.
+
+## Searching for an epic from epics list page
+
+> Introduced in [GitLab Ultimate][ee] 10.5.
+
+You can search for an epic from the list of epics using filtered search bar (similar to
+that of Issues and Merge requests) based on following parameters:
+
+- Title or description
+- Author name / username
+- Labels
+
+![epics search](img/epics_search.png)
+
+To search, go to the list of epics and click on the field **Search or filter results...**.
+It will display a dropdown menu, from which you can add an author. You can also enter plain
+text to search by epic title or description. When done, press <kbd>Enter</kbd> on your
+keyboard to filter the list.
+
+You can also sort epics list by:
+
+- **Created date**
+- **Last updated**
+- **Start date**
+- **Due date**
+
+Each option contains a button that can toggle the order between **ascending** and **descending**. The sort option and order will be persisted to be used wherever epics are browsed including the [roadmap](../roadmap/index.md).
+
+![epics sort](img/epics_sort.png)
+
+## Permissions
+
+If you have access to view an epic and have access to view an issue already
+added to that epic, then you can view the issue in the epic issue list.
+
+If you have access to edit an epic and have access to edit an issue, then you
+can add the issue to or remove it from the epic.
+
+Note that for a given group, the visibility of all projects must be the same as
+the group, or less restrictive. That means if you have access to a group's epic,
+then you already have access to its projects' issues.
+
+You may also consult the [group permissions table][permissions].
