# Introduction

ZoraOS is a suite of developer tools that allow anyone to build on the Zora Protocol. The vision for ZoraOS is to build high quality tools across the entire development stack. We want to enable developers to explore new and interesting ideas for an Internet Renaissance. ZoraOS consists of three primary components:

{% content-ref url="dev/smart-contracts" %}
[smart-contracts](https://ourzora.gitbook.io/zoraos/dev/smart-contracts)
{% endcontent-ref %}

{% content-ref url="dev/zdk" %}
[zdk](https://ourzora.gitbook.io/zoraos/dev/zdk)
{% endcontent-ref %}

{% content-ref url="dev/subgraph" %}
[subgraph](https://ourzora.gitbook.io/zoraos/dev/subgraph)
{% endcontent-ref %}

{% content-ref url="dev/media-rendering/nft-hooks" %}
[nft-hooks](https://ourzora.gitbook.io/zoraos/dev/media-rendering/nft-hooks)
{% endcontent-ref %}

In the spirit of building tools in collaboration with our community, all of our repositories are open source with either the [MIT License](https://opensource.org/licenses/MIT) or the [GPL-3.0 License](https://www.gnu.org/licenses/gpl-3.0.en.html). Zora is a tool in the public domain – as such, anyone and everyone is able to contribute and improve Zora for the entire community. 

Beyond our developer tools, this site also hosts guides for developers to follow, such as [connecting to a wallet](https://ourzora.gitbook.io/zoraos/guides/connect-to-a-wallet) or [building a marketplace](https://ourzora.gitbook.io/zoraos/guides/build-a-marketplace), and links to our [Discord community](https://ourzora.gitbook.io/zoraos/community/discord) and [Platforms using Zora](https://ourzora.gitbook.io/zoraos/community/platforms-using-zora).
