 ## Prettier + TSLint
 
-We have an active discussion on Linting [here](https://github.com/sw-yx/react-typescript-cheatsheet/issues/7).
+*Contributed by: [@azdanov](https://github.com/sw-yx/react-typescript-cheatsheet/pull/14)*
+
+To use prettier with TSLint you will need [`tslint-config-prettier`](https://github.com/alexjoverm/tslint-config-prettier) which disables all the 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>
+        </th>
+    </tr>
+    <tr>
+        <td>
+            <pre>
+{

+
+## ESLint + TSLint
+
+Why? ESLint ecosystem is rich, with lots of different plugins and config files, whereas TSLint tend to lag behind in some areas.
+
+To remedy this nuisance there is an [`eslint-typescript-parser`](https://github.com/eslint/typescript-eslint-parser) which tries to bridge the differences between javascript and typescript. It still has some rough corners, but can provide consistent assistance with certain plugins.
