# Start the JMap NG Core library
You can start JMap NG Core in a div of your website, or as a full page application.
## Import the library from CDN
To use the JMap NG Core library, simply import the JMap NG Core Javascript library from our CDN link.
```html
```
Make sure the version of the library matches the version of your JMap Server instance.
## Set library options
You have to specify options to the library:
```javascript
window.JMAP_OPTIONS = {
projectId: 1,
restBaseUrl: "https://jmapdoc.jmaponline.net/services/rest/v2.0",
anonymous: true,
map: {
containerId: "my-custom-map",
zoom: 9.757829447748511,
center: {
x: -73.60243569463414,
y: 45.504533166207324
},
scaleControlVisible: true,
scaleControlPosition: "top-right"
}
}
```
