 These are generated outputs meant for operator review before use in production.

+### Generator output selection (interactive + automation)
+
+The brownfield generator defaults to Terraform output `dynu_dns_records`:
+
+```bash
+python3 scripts/generate-brownfield-records.py --dry-run
+```
+
+If the default output is missing/unusable and stdin is interactive, the script shows a picker of available Terraform outputs and indicates which ones are usable for DNS imports.
+
+```bash
+# Interactive mode: choose from available Terraform outputs
+python3 scripts/generate-brownfield-records.py --dry-run
+
+# Non-interactive mode: specify output explicitly
+python3 scripts/generate-brownfield-records.py \
+  --records-output dynu_dns_inventory \
+  --dry-run
+
+# Disable menu and fail fast
+python3 scripts/generate-brownfield-records.py \
+  --no-interactive \
+  --dry-run
+
+# Use saved terraform output JSON and choose interactively
+terraform output -json > generated/terraform-output.json
+python3 scripts/generate-brownfield-records.py \
+  --from-file generated/terraform-output.json \
+  --dry-run
+```
+
+Notes:
+
+- The menu shows Terraform outputs currently stored in state.
+- If newly added outputs do not appear, run:
+
+```bash
+terraform apply -refresh-only
+```
+
+- The selected output must contain real Dynu provider record fields:
+  - `id`
+  - `domain_id`
+  - `hostname`
+  - `record_type`
+
 ## Troubleshooting

 ### Plan shows a large wall of `+` values under outputs
