-As of v2.3 you can now override the test blocks and focus functions.
+If the testing framework you use doesn't use `.only` to focus tests, you can override the matchers with [options](#options).
 
 ## Installation
 
-First you'll need to install [ESLint](http://eslint.org) then the plugin:
+[Install ESLint](https://eslint.org/docs/user-guide/getting-started) if you haven't done so already, then install `eslint-plugin-no-only-tests`:
 
 ```bash
-npm install --save-dev eslint eslint-plugin-no-only-tests
+npm install --save-dev eslint-plugin-no-only-tests
 # or
-yarn add --dev eslint eslint-plugin-no-only-tests
+yarn add --dev eslint-plugin-no-only-tests
 ```
 
 > **Note:** If you installed ESLint globally (using the `-g` flag) then you must also install `eslint-plugin-no-only-tests` globally.
