# Introduction
> **NOTE**:
> Carta has recently been updated to `v4`, which features numerous major changes.
>
> Follow the [Migration Guide](http://beartocode.github.io/carta/migration) to update your project.
Carta is a **lightweight**, **fast** and **extensible** Svelte Markdown editor and viewer. It is powered by [unified](https://github.com/unifiedjs/unified), [remark](https://github.com/remarkjs/remark) and [rehype](https://github.com/rehypejs/rehype). Check out the [examples](http://beartocode.github.io/carta/examples) to see it in action.

> Checkout the documentation for an example.
