+/**
+ * This file sets you up with structure needed for an ESLint rule.
+ *
+ * It leverages utilities from @typescript-eslint to allow TypeScript to
+ * provide autocompletions etc for the configuration.
+ *
+ * Your rule's custom logic will live within the create() method below
+ * and you can learn more about writing ESLint rules on the official guide:
+ *
+ * https://eslint.org/docs/developer-guide/working-with-rules
+ *
+ * You can also view many examples of existing rules here:
+ *
+ * https://github.com/typescript-eslint/typescript-eslint/tree/master/packages/eslint-plugin/src/rules
