+# Merge Request discussion resolution
+
+> [Introduced][ce-5022] in GitLab 8.11.
+
+Discussion resolution helps keep track of progress during code review.
+Resolving comments prevents you from forgetting to address feedback and lets you
+hide discussions that are no longer relevant.
+
+!["A discussion between two people on a piece of code"][discussion-view]
+
+Comments and discussions can be resolved by anyone with at least Developer
+access to the project, as well as by the author of the merge request.
+
+## Marking a comment or discussion as resolved
+
+You can mark a discussion as resolved by clicking the "Resolve discussion"
+button at the bottom of the discussion.
+
+!["Resolve discussion" button][resolve-discussion-button]
+
+Alternatively, you can mark each comment as resolved individually.
+
+!["Resolve comment" button][resolve-comment-button]
+
+## Jumping between unresolved discussions
+
+When a merge request has a large number of comments it can be difficult to track
+what remains unresolved. You can jump between unresolved discussions with the
+Jump button next to the Reply field on a discussion.
+
+You can also jump to the first unresolved discussion from the button next to the
+resolved discussions tracker.
