# Developers

Sipster Design System contains a handful of modular NPM packages that developers can implement in their projects. Currently there are three main packages:

* [SDS Core](https://www.npmjs.com/package/@sipster/core)
* [SDS Telicon](https://www.npmjs.com/package/@sipster/telicon)
* [SDS Themes](https://www.npmjs.com/package/@sipster/themes)

These are the base packages a developer might need to implement SDS on their projects beside the collection of components created for React library. See the complete list of components [here](/sds/sds-3.0/sds-components/components.md):
