+# Ansible-lint is able to recognize and load skip rules stored inside
+# `.ansible-lint-ignore` (or `.config/ansible-lint-ignore.txt`) files.
+# To skip a rule just enter filename and tag, like "playbook.yml package-latest"
+# on a new line.
+# Optionally you can add comments after the tag, prefixed by "#". We discourage
+# the use of skip_list below because that will hide violations from the output.
+# When putting ignores inside the ignore file, they are marked as ignored, but
+# still visible, making it easier to address later.
