+FoalTS comes up with a pre configuration for the linter [ESLint](https://eslint.org/) with [typescript-eslint](https://typescript-eslint.io/).
 
-> *TSLint is an extensible static analysis tool that checks TypeScript code for readability, maintainability, and functionality errors. It is widely supported across modern editors & build systems and can be customized with your own lint rules, configurations, and formatters.*
+> *ESLint is an open source project originally created by Nicholas C. Zakas in June 2013. Its goal is to provide a pluggable linting utility for JavaScript..*

-This configuration is stored in the json file `tslint.json`.
+> * `@typescript-eslint/parser` - An ESLint-specific parser which leverages `typescript-estree` and is designed to be used as a replacement for ESLint's default parser, `espree`.
+> * `@typescript-eslint/eslint-plugin` - An ESLint-specific plugin which, when used in conjunction with `@typescript-eslint/parser`, allows for TypeScript-specific linting rules to run.

+
+Previously, FoalTS used TSLint, but it has since been [deprecated](https://medium.com/palantir/tslint-in-2019-1a144c2317a9).
+
+> In order to avoid bifurcating the linting tool space for TypeScript, we therefore plan to deprecate TSLint and focus our efforts instead on improving ESLint’s TypeScript support.

 You can run the linting with this command:
 ```sh
 npm run lint
 ```
+
+And if the linting issues can be fixed, you can also fix them with this command:
+```sh
+npm run lint:fix
