+# This file defines an Azure Pipeline build for testing Flink. It is intended to be used
+# with a free Azure Pipelines account.
+# It has the following features:
+#  - default builds for pushes / pull requests
+#  - end-to-end tests
+#
+#
+# For the "apache/flink" repository, we are using the pipeline definition located in
+#   tools/azure-pipelines/build-apache-repo.yml
+# 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.
