+# We recommend you run this as a pre-push hook: to reduce
+# review turn-around time, we want all pushes to run tasks
+# locally. Using this hook will guarantee your hook gets
+# updated as the repository changes.
+#
+# This hook tries to run as much as possible without taking
+# too long.
+#
+# You can use it by running this command from the project root:
+# `ln -s ../../tools/pre-push-recommended.sh .git/hooks/pre-push`
+
+# Descriptions for each gradle task below can be found in the
+# output of `./gradlew tasks`.
