# Installation
Using npm
```bash
npm i @youcan/js
```
Or you can use cdn
```html
```
***
# Usage
### npm
```ts
import youcanjs from '@youcan/js';
const youcan = youcanjs.init();
const categories = await youcanjs.category.fetchAll();
```
### CDN
In order for the sdk to work properly, it's highly recomended to place the script tag at the end of the head tag.
If you're using liquid template engine for the theme, make sure to place the SDK script tag after the `content_for_header` tag.
```html
...
{{ content_for_header }}
...
...
```
