## Installation Guide

### NodeJS

You can add the SDK as a dependency using [NPM](https://www.npmjs.com/package/@flagship.io/js-sdk) or [YARN](https://yarn.pm/@flagship.io/js-sdk)

```shell
yarn add @flagship.io/js-sdk
```

```shell
npm install @flagship.io/js-sdk
```

### CDN

You can also install via a CDN

```html
<script src="https://cdn.jsdelivr.net/npm/@flagship.io/js-sdk/dist/index.browser.js"></script>
```

### Deno

For Deno, there are 2 methods:

* Use URLs for dependency management, just add the deno.land URL

```typescript
import { Flagship } from "https://deno.land/x/flagship_io_js_sdk/mod.ts";
```

* Or use [import maps](https://github.com/WICG/import-maps)

```json
{
   "imports": {
      "@flagship.io/js-sdk": "https://deno.land/x/flagship_io_js_sdk/mod.ts"
   }
}
```
