 ## Installation
+
 ```sh
 npm install overlayscrollbars-ngx
 ```
 
 ## Peer Dependencies
+
 OverlayScrollbars for Angular has the following **peer dependencies**:
+
 - The vanilla JavaScript library: [overlayscrollbars](https://www.npmjs.com/package/overlayscrollbars)
+
 ```
 npm install overlayscrollbars
 ```
+
 - The Angular framework: [@angular/core](https://www.npmjs.com/package/@angular/core)
+
 ```
 npm install @angular/core
 ```
+
 ## TypeScript
+
 - In case you are using TypeScript, you have to install the [OverlayScrollbars typings](https://www.npmjs.com/package/@types/overlayscrollbars):
+
 ```
 npm install @types/overlayscrollbars
 ```
+
 Since this wrapper is written in TypeScript it comes with its generated typings.<br>
 Check out the [recommended](https://github.com/KingSora/OverlayScrollbars#typescript) **tsconfig.json** options.
 
 ## Usage
+
 #### CSS
+
 You have to import the `OverlayScrollbars.css` by yourself.<br>
 The component **doesn't** do it for you as the styles are **global styles**!<br>
 There are different ways to achieve this, in Angular the most simple way for me was to add [this line](https://github.com/KingSora/OverlayScrollbars/blob/master/packages/overlayscrollbars-ngx/example/src/styles.css#L1) in the `styles` file:
+
 ```css
-@import '~overlayscrollbars/css/OverlayScrollbars.css';
+@import "~overlayscrollbars/css/OverlayScrollbars.css";
 ```
 
 #### Import
+
 First you need to import the module into your modules file:
+
 ```ts
-import { NgModule } from '@angular/core';
+import { NgModule } from "@angular/core";
-import { OverlayscrollbarsModule } from 'overlayscrollbars-ngx';
+import { OverlayscrollbarsModule } from "overlayscrollbars-ngx";
 
 @NgModule({
-  imports: [ OverlayscrollbarsModule ]
+  imports: [OverlayscrollbarsModule],
 })
-export class AppModule { }
+export class AppModule {}
 ```
+
 After that you can import the component into your file(s):
+
 ```ts
-import { OverlayScrollbarsComponent } from 'overlayscrollbars-ngx';
+import { OverlayScrollbarsComponent } from "overlayscrollbars-ngx";
 ```
 
 #### Template
+
 After the import you can use it in templates like:
+
 ```html
-<overlay-scrollbars>
+<overlay-scrollbars> example content </overlay-scrollbars>
-  example content
-</overlay-scrollbars>
 ```
 
 #### Properties
+
 Two properties are accepted: `options` and `extensions`.
+
 - The `options` property accepts a `object` and can be changed at any point in time, and the plugin will adapt.
 - The `extensions` property accepts a `string`, `string array` or `object` and is only taken into account if the component gets mounted.

 You can read more about the `options` object [here](https://kingsora.github.io/OverlayScrollbars/#!documentation/options), `extensions` are documented [here](https://kingsora.github.io/OverlayScrollbars/#!documentation/extensions-basics) and [here](https://kingsora.github.io/OverlayScrollbars/#!documentation/initialization).
 
 #### Instance
+
 If you get the component reference, it provides two methods: `osInstance()` and `osTarget()`.
+
 - The `osInstance()` method returns the OverlayScrollbars `instance` of the component, or `null` if the instance isn't initialized yet or already destroyed.
 - The `osTarget()` method returns the native `html` element to which the plugin was initialized, or `null` if the the component isn't mounted yet or already unmounted.
 
 ## Example App
+
 In case you need a example app for reference, you can use the example app in this repo(`example folder`):
+
 - [Live example](https://kingsora.github.io/OverlayScrollbars/frameworks/angular/)
 - [Source code](https://github.com/KingSora/OverlayScrollbars/tree/master/packages/overlayscrollbars-ngx/example)
 
 If you wanna build the example app, run these commands:
