#################################################################################################

individual commits).
+ alwaysUsePrTitle: false
+ # If set to true, it will only check the commit in case there is a single
commit.
+ # In case of multiple commits it will check PR title.
+ # This reflects the standard behaviour of Github that for `Squash & Merge`
GitHub
+ # uses the PR title rather than commit messages for the squashed commit
¯\_(ツ)_/¯
+ # For single-commit PRs it takes the squashed commit message from the commit
as expected.

do not squash commits at merge.

and ${regex} (the titleRegexp above).

+# Various Flags to control behaviour of the "Labeler"
+labelerFlags:
+ # If this flag is changed to 'false', labels would only be added when the PR
