+# INSTALL THIS FILE IN: LambdaTest/documentation  ->  .github/workflows/documentation-notify.yml
+# (It does NOT belong in product-context's own .github/workflows — it is the
+#  *sender* that lives in the docs repo. It is kept here only as the canonical copy.)
+#
+# Purpose: when a PR merges into the `stage` branch, notify product-context to
+#          re-crawl the affected product docs (Loop 2 of the auto-update system).
+#
+# One-time setup in LambdaTest/documentation:
+#   Settings -> Secrets and variables -> Actions -> New repository secret
+#     Name:  PRODUCT_CONTEXT_DISPATCH_TOKEN
+#     Value: a fine-grained PAT / GitHub App token with contents:write (dispatch)
+#            on LambdatestIncPrivate/product-context
