UI copy update MR empty state to help platform switchers understand GitLab terminology

Problem to solve

Growth is working on improving new-user onboarding.

UX research shows that GitLab-specific terminology increases the learning curve for new users from other platforms.

Confusion about the term Merge requests came up in multiple sessions. (UXR slide). Project was also a confusing term.

Proposal to discuss

Figma file

• Re-word the first-time empty state to help first-time users understand what a MR is (https://.gitlab.com/group/project/-/merge_requests)
  • The first-time empty state is shown when there have never been MRs. This issue does not touch the "No open MRs" empty state (screenshot)
• Remove the Email a MR from the empty state to keep the empty state focused on the primary use case (no events fired in the last 30 days)

Current empty state	Proposed empty state
