+## Mocha and Chai
+
+Cypress is built on top of [Mocha](https://on.cypress.io/guides/references/bundled-libraries#Mocha) and [Chai](https://on.cypress.io/guides/references/bundled-libraries#Chai). See the following sections for information on using ESLint plugins [eslint-plugin-mocha](https://www.npmjs.com/package/eslint-plugin-mocha) and [eslint-plugin-chai-friendly](https://www.npmjs.com/package/eslint-plugin-chai-friendly) together with `eslint-plugin-cypress`.
+
+## Mocha `.only` and `.skip`
+
+During test spec development, [Mocha exclusive tests](https://mochajs.org/#exclusive-tests) `.only` or [Mocha inclusive tests](https://mochajs.org/#inclusive-tests) `.skip` may be used to control which tests are executed, as described in the Cypress documentation [Excluding and Including Tests](https://on.cypress.io/guides/core-concepts/writing-and-organizing-tests#Excluding-and-Including-Tests). To apply corresponding rules, you can install and use [eslint-plugin-mocha](https://www.npmjs.com/package/eslint-plugin-mocha). The rule [mocha/no-exclusive-tests](https://github.com/lo1tuma/eslint-plugin-mocha/blob/main/docs/rules/no-exclusive-tests.md) detects the use of `.only` and the [mocha/no-skipped-tests](https://github.com/lo1tuma/eslint-plugin-mocha/blob/main/docs/rules/no-skipped-tests.md) rule detects the use of `.skip`:
+
+```sh
+npm install --save-dev eslint-plugin-mocha
+```
+
+In your `.eslintrc.json`:
+
+```json
+{
+  "plugins": [
+    "cypress",
+    "mocha"
+  ],
+  "rules": {
+    "mocha/no-exclusive-tests": "warn",
+    "mocha/no-skipped-tests": "warn"
+  }
+}
+```
 
-**NOTE**: These rules currently require eslint 5.0 or greater. If you would like support added for eslint 4.x, please 👍  [this issue](https://github.com/cypress-io/eslint-plugin-cypress/issues/14).
+Or you can simply use the `cypress/recommended` and `mocha/recommended` configurations together, for example:

-## Assertion Before Screenshot
+# Require screenshots to be preceded by an assertion (`cypress/assertion-before-screenshot`)

 If you take screenshots without assertions then you may get different screenshots depending on timing.
 
 For example, if clicking a button makes some network calls and upon success, renders something, then the screenshot may sometimes have the new render and sometimes not.
 
+## Rule Details
+
 This rule checks there is an assertion making sure your application state is correct before doing a screenshot. This makes sure the result of the screenshot will be consistent.
