# Installation
Installation is easy, whether through NPM or CDN.
## **Installation with NPM**
For installation with npm, the requirement is to have **nodejs** and **npm** installed. For more documentation on this aspect, see here:
Once this step is completed, installation is very simple; in your repository's command line, run:
```bash
npm install @facephi/landing-sdk
```
This will add the SDK to your project for use as follows:
```javascript
import LandingSDKClient from '@facephi/landing-sdk';
const landingSDK = new LandingSDKClient('YOUR_APIKEY');
```
Where the API key will be provided by us or generated by you through the Landing Builder.
To invoke the POST, we will use the following command:
```javascript
landingSDK.callLanding();
```
For example:
```html
Landing SDK Client
```
***
## **Installation with CDN**
Installation from CDN is very simple, since you don't have to perform any prior installation steps, just add it as follows:
```html
Landing SDK Client
```
***
## Use via iframe
If you use the components inside a **iframe** it is recommended **to keep the focus within the container** that integrates the SDK Web components.
