+## Selective Testing
+
+If you only generate a subset of your snapshots per CI run — for example, because you run only affected tests or shard across parallel jobs — pass the `--selective` flag on each upload:
+
+```bash
+sentry-cli build snapshots ./shard-1 --app-id web-frontend --selective
+sentry-cli build snapshots ./shard-2 --app-id web-frontend --selective
+```
+
+When an upload is marked as selective, Sentry only diffs the snapshots you uploaded. Any snapshot that exists in the base build but was not included in the upload is treated as **unchanged** (skipped) rather than removed. Sentry merges selective uploads that share the same commit SHA and `app-id`, so you can upload shards independently and they combine into a single build.

+<Alert level="warning">
+  Because Sentry cannot distinguish a deliberately deleted snapshot from one
+  that was not part of the subset, removals and renames cannot be detected when
+  using `--selective`.
