+## Prettier
+
+[Prettier](https://www.npmjs.com/package/prettier) is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it
+with its own rules that take the maximum line length into account, wrapping code when necessary.
+
+Run ``prettier`` linter, executing the following command:
+
+  ```bash
+  make prettier
+  ```
+
+To fix the ``prettier`` warnings, execute the following command:
+
+  ```bash
+  make prettier-fix
+  ```
+
+---
+
+## Eslint
+
+[ESLint](https://www.npmjs.com/package/eslint) is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code.
+
+Eslint should run just fine using the setup config from any Volto projects generated by `volto project generator`.
+
+If for some reason that doesn't work, and you need to manually install eslint,
+you can also use the following steps to install eslint.
+
+For installing ``eslint``, execute the following command:
+
+  ```bash
+  yarn add --dev eslint eslint-plugin-jsx-a11y eslint-plugin-prettier eslint-plugin-react-hooks eslint-plugin-import eslint-plugin-flowtype
+  ```
+
+For setting up ``eslint``, execute the following command:
+
+  ```bash
+  cp .project.eslintrc.js .eslintrc.js
+  ```
+
+Run ``eslint``, executing the following command:
+
+  ```bash
+  make lint
+  ```
+
+To fix the problems found by ``eslint``, execute the following command:
+
+  ```bash
+  make lint-fix
+  ```
+
+---
+
+## Stylelint
+
+[Stylelint](https://www.npmjs.com/package/stylelint) is a mighty CSS linter that helps you avoid errors and enforce conventions.
+
+For installing ``stylelint``, execute the following command:
+
+  ```bash
+  yarn add --dev stylelint
+  ```
+
+To run ``stylelint``, execute the following command:
+
+  ```bash
+  make stylelint
+  ```
+
+If you need to run ``stylelint`` on styles found in .overrides files, execute the following command:
+
+  ```bash
+  make stylelint-overrides
+  ```
+
+To auto fix the found issues by ``stylelint``, execute the following command:
+
+  ```bash
+  make stylelint-fix
