# Getting Started

*router5* is available in all major formats: **ES6**, **CommonJS**, and **UMD**. It can be installed using **npm** or **yarn**. Alternatively, you can download a specific version from [github](https://github.com/router5/router5/releases).

## Installation

```
# yarn
yarn add router5
# npm
npm install router5
```

## Include router5 in your application

### ES2015 syntax

```javascript
// ES2015+
import createRouter from 'router5';

import browserPlugin from 'router5-plugin-browser';
import persistentParamsPlugin from 'router5-plugin-persistent-params';
```

### CommonJS syntax

```javascript
var createRouter = require('router5').default;
var browserPlugin = require('router5-plugin-browser');
var persistentParamsPlugin = require('router5-plugin-persistent-params');
```

### UMD

Various UMD bundles are accessible under `/dist/umd`: you should use them for AMD or global. The router5 bundle contains all *router5* dependencies (*route-node* and *path-parser*), but doesn't contain plugins.
