-# Approval for merge requests
-
-Usually you accept merge request if it is ready and reviewed. But in certain 
-cases you want to be sure that every merge request will be reviewed by several 
-people before it gets merged. You can use GitLab approve feature for enforcing such 
-workflow. To enable it you should go to project settings page and set 
-"Approvals required" field to numeric value. For example if you set it to number 3 
-that means each merge request should receive 3 approves from different people 
-before it can be merged via user interface.
-

-
-After you set approves value you can see on merge request page "Approve" button
-instead of "Accept" one. As soon as merge request get enough approvals it will 
-be available for merge with user interface.

+# Merge Request Approvals
+
+If you want to make sure every merge request is approved by one or more
+people, you can enforce this workflow by using merge request approvals.
+Merge request approvals allow you to set the number of necessary approvals
+and predefine a list of approvers that will need to approve every
+merge request in a project.
+
+![Merge request approval](merge_request_approvals/2_approvals.png)
+
+## Configuring Approvals
+
+You can configure the approvals in the project settings, under merge requests.
+
+![Merge Request Approvals in Project Settings](merge_request_approvals/approvals_settings.png)
+
+To enable it, set **Approvals required** to 1 or higher.
+
+### Approvals Required
+
+This sets the amount of approvals required before being able to merge a merge request.
+At 0, this disables the feature. Any value above requires that amount of different
+users to approve the merge request.
+
+### Reset approvals on push
+
+With this setting turned on, approvals are reset when a new push
+is done to the merge request branch.
+
+Turn "Reset approvals on push" off if you want approvals to persist,
+independent of changes to the merge request.
+
+### Approvers
+
+At approvers you can define the default set of users that need to approve a
+merge request.
+
+If there are more approvers than required approvals, any subset of these users
+can approve the merge request.
+
+If there are less approvers than required approvals, all the set approvers plus
+any other user(s) need to approve the merge request before being able to merge it.
+
+![One specific user and someone else need to approve this merge request](merge_request_approvals/1_named_approval.png)
+
+If the approvers are equal to the amount of required approvals, all the approvers are
+required to approve merge requests.
+
+![Two specific users need to approve this merge request](merge_request_approvals/2_named_approvals.png)
+
+Note that approvers can be changed during merge request creation.
+
+## Using Approvals
+
+After configuring Approvals, you will see the following during merge request creation.
+
+![Choosing approvers in merge request creation](merge_request_approvals/approvals_mr.png)
+
+You can change the default set of approvers before creating the merge request.
+You can't change the amount of required approvals. This ensures that you're
+not forced to adjust settings when someone is unavailable for approval, yet
+the process is still enforced.
+
+To approve a merge request, simply press the button.
