+#
+# For the "apache/flink" repository, we are using the pipeline definition located in

+# That file points to custom, self-hosted build agents for faster pull request build processing and 
+# integration with Flinkbot.
+# The custom pipeline definition file is configured in the "Pipeline settings" screen
+# of the Azure Pipelines web ui.
