+# 2. Add any additional environment variables as needed
+# 3. To attach S3 IAM policies from shared state:
+#    - Uncomment the S3 policy attachment section below
+#    - Update the policy_arn to match the output from shared/main.tf
+#    - Available shared outputs (examples):
+#      - data.terraform_remote_state.shared.outputs.condition_etl_s3_read_arn
+#      - data.terraform_remote_state.shared.outputs.postcode_splitter_s3_read_arn
+# 4. To create a NEW S3 policy:
+#    - Add a new module "lambda_s3_policy" in shared/main.tf using the
+#      s3_iam_policy module (see examples in shared/main.tf)
+#    - Then reference it here using data.terraform_remote_state.shared.outputs
