 We have an active discussion on Linting [here](https://github.com/sw-yx/react-typescript-cheatsheet/issues/7).
 
+To user prettier with TSLint you will need [`tslint-config-prettier`](https://github.com/alexjoverm/tslint-config-prettier) which disables all conflicting rules and optionally [`tslint-plugin-prettier`](https://github.com/ikatyang/tslint-plugin-prettier) which will highlight differences as TSLint issues.

+Example configuration:
+
+<table>
+    <tr>
+        <th>
+            <strong>tslint.json</strong>
+        </th>
+        <th>
+            <strong>.prettierrc</strong>
