# Where to find ApiRTC library?

## NPM Package manager

If you develop in the NodeJS ecosystem, you can use the NPM packet manager.

1. Open a terminal or command line interface
2. Go to your project folder `cd my_project_folder`
3. Install the latest ApiRTC library in your node\_module folder:

```bash
npm install @apirtc/apirtc
```

To install a specific version of ApiRTC, add the version tag at the end.

For example, using the version 4.6.1 would be:

```bash
npm install @apirtc/apirtc@4.6.1
```

## CDN - Direct access via URL
