# "Work In Progress" Merge RequestsTo prevent merge requests from accidentally being accepted before they're completely ready, GitLab blocks the "Accept" button for merge requests that have been marked a **Work In Progress**.![Blocked Accept Button](wip_merge_requests/blocked_accept_button.png)To mark a merge request a Work In Progress, simply start its title with `[WIP]` or `WIP:`.![Mark as WIP](wip_merge_requests/mark_as_wip.png)To allow a Work In Progress merge request to be accepted again when it's ready, simply remove the `WIP` prefix.![Unark as WIP](wip_merge_requests/unmark_as_wip.png)
