--- sidebar_title: Core Features sidebar_position: 25 --- # Concepts `zrok` was designed to make sharing local resources both secure and easy. In this section of the `zrok` documentation, we'll tour through all of the most important features. Sharing with `zrok` can be either [`public`](./sharing-public.md) or [`private`](./sharing-private.md). Naturally, regular web-based resources can be shared but `zrok` also includes support for sharing raw [TCP](./tunnels.md) and [UDP](./tunnels.md) network connections, and also includes a [website and file sharing](./files.md) feature. Learn about `zrok` [hosting here](./hosting.md), including instructions on how to [install your own `zrok` instance](../guides/self-hosting/self_hosting_guide.md).
