+# This is an auto-generated file. Please don't edit this file directly.
+
+# This file is automatically generated by merging two files:
+# 1. The Exercism-wide labels: defined in https://github.com/exercism/org-wide-files/blob/main/synced-files/.github/labels.yml)
+# 2. The repository-specific labels: defined in a `.appends/.github/labels.yml` file (optional)
+#
+# If you want to use additional labels besides the Exercism-wide labels,
+# don't edit this file directly but instead create a `.appends/.github/labels.yml`
+# file within this repo.
+#
+# Any changes to the repo's `.appends/.github/labels.yml` file or the
+# Exercism-wide `labels.yml` file will automatically result in this file being
+# regenerated and the labels being updated. This typically takes 5-10 minutes.
