+
+```yaml
+- repo: https://github.com/golangci/misspell
+  rev: v0.6.0
+  hooks:
+    - id: misspell
+      # The hook will run on all files by default.
+      # To limit to some files only, use pre-commit patterns/types
+      # files: <pattern>
+      # exclude: <pattern>
+      # types: <types>
