+![ESLint Flow Demo](https://github.com/amilajack/eslint-plugin-flowtype-errors/blob/master/flow-demo.gif?raw=true)
 
 ## Why?
+
 * **Lower barrier:** Any editor that has ESLint support now supports Flow 🎉
 * **Less editor configuration:** No need to change your entire workflow to incorporate flow. No multiple-linters-per-file nonsense.
 * **Simple:** Its literally just an ESLint rule! Just install the dependency, add a flowconfig, and you're good to go!
 
 ## Getting Started
+
 This guide assumes that you have installed eslint, babel, babel-plugin-transform-flow-strip-types and configured flow. Check out the [from-scratch guide](https://github.com/amilajack/eslint-plugin-flowtype-errors/wiki/Getting-Started) for the full guide on getting started.
 
-⚠️ Make sure the 64-bit version of your texteditor/IDE. For atom, [see this comment](https://github.com/amilajack/eslint-plugin-flowtype-errors/issues/40#issuecomment-275983387)

-**Step 1. Install**
+### **1. Install**
 
 ```bash
 npm install --save-dev eslint-plugin-flowtype-errors
 ```
 
-**Step 2. Configure**
-
-Add this line to the 'rules' section of your `.eslintrc` to report flow errors.
-```js
-"flowtype-errors/show-errors": "error"
-```
-
-Add this line to the 'rules' section of your `.eslintrc` to report flow warnings.
-```js
-"flowtype-errors/show-warnings": "warn"
-```
-Note that flow won't report warnings unless you add this setting to your `.flowconfig`:
-```toml
-[options]
-include_warnings=true
-```
-
-Add this line to the 'rules' section of your `.eslintrc` to enforce a minimum percentage of flow coverage per file (optional). Here's an example of enforcing a converage of at least 50%:
-```js
-"flowtype-errors/enforce-min-coverage": ["error", 50]
-```
+### **2. Configure**
 
-Add this line to the 'plugins' section of your `.eslintrc`
-```js
-"flowtype-errors"
+Extend the recommended config:
+```jsonc
+{
+  "extends": ["plugin:flowtype-errors/recommended"]
+}
 ```
 
-Add the `@flow` pragma to files that you want to lint
-Also make sure that your `.flowconfig` is in the root of your project directory
-```js
-/**
- * @flow
- */
-```
-
-**Step 3. Settings (optional)**
-
-Add this line to the 'settings' section of your `.eslintrc` to force the Flow server to stop after it finishes checking types.
-
-```js
-"settings": {
-  "flowtype-errors": {
-    "stopOnExit": true
-  }
-},
-```
-
-**Step 4. Lint**
-
-Run `eslint` and you're all set!

-## Planned Implementations
-* Add more extensive tests
-* Allow passing arguments to flow binary
-* Run flow minimal amount of times for faster linting
-* Custom formatting of flow error messages
-* Enable rules to allow and disallow specific flow errors
