 /**
  * Sample Temporal workflow that demonstrates setting up, updating, and retrieving workflow search
  * attributes using the typed search attributes API.
+ *
+ * <p>NOTE: you may need to add these custom search attributes yourself before running the sample.
+ * If you are using autosetup image for service, you will need to create the
+ * "CustomKeywordListField" search attribute with Temporal cli, for example:
+ *
+ * <p>temporal operator search-attribute create -name "CustomKeywordListField" -type "KeywordList"
+ *
+ * <p>If you run your test and don't have some custom SA defined that are used here you would see
+ * error like: INVALID_ARGUMENT: Namespace default has no mapping defined for search attribute
+ * CustomBoolField when trying to start the workflow execution. In that case use cli to add the
+ * needed search attribute with its needed type.
