+# This is a mapping of labels to title/description regex patterns used by
+# https://github.com/github/issue-labeler to automatically add labels to issues
+# when opened/edited.
+#
+# If multiple patterns are provided in the list for a label, they all have to
+# match. A label can only occur once.
+#
+# To label when any one of multiple patterns matches, concatenate the patterns
+# using a "|" delimeter, to form a single pattern.
+#
+# "^" appears to match only the beginning of the issue title.
+#
+# Automatic label removal is currently disabled, because it also removes
+# manually added labels that didn't have matches.
