+MERGE DIFF RESOLUTION                                       *diffs-merge*
+
+When pressing `du`/`dU` on an unmerged (`U`) file in the fugitive status
+buffer, diffs.nvim opens a unified diff of ours (`git show :2:path`) vs
+theirs (`git show :3:path`) with full treesitter and intra-line highlighting.
+
+The same conflict resolution keymaps (`doo`/`dot`/`dob`/`don`/`]x`/`[x`)
+are available on the diff buffer. They resolve conflicts in the working
+file by matching diff hunks to conflict markers:
+
+- `doo` replaces the conflict region with ours content
+- `dot` replaces the conflict region with theirs content
+- `dob` replaces with both (ours then theirs)
+- `don` removes the conflict region entirely
+- `]x`/`[x` navigate between unresolved conflict hunks
+
+Resolved hunks are marked with `(resolved)` virtual text. Hunks that
+correspond to auto-merged content (no conflict markers) show an
+informational notification and are left unchanged.
+
+The working file buffer is modified in place; save it when ready.
+Phase 1 inline conflict highlights (see |diffs-conflict|) are refreshed
+automatically after each resolution.
