+    /// Biome ignore comments cannot be used because the rule applies on filenames not file contents.
+    /// To ignore files, you can use [`overrides`](https://biomejs.dev/reference/configuration/#overrides).
+    /// If you want to ignore all files in the `test` directory, then you can disable the rule for those files only:
+    ///
+    /// ```json
+    /// {
+    ///   "overrides": [
