+👋 Hi! This file was autogenerated by tslint-to-eslint-config.
+https://github.com/typescript-eslint/tslint-to-eslint-config
+
+It represents the closest reasonable ESLint configuration to this
+project's original TSLint configuration.
+
+We recommend eventually switching this configuration to extend from
+the recommended rulesets in typescript-eslint.
+https://github.com/typescript-eslint/tslint-to-eslint-config/blob/master/docs/FAQs.md
+
+Happy linting! 💖
