## What is KOReader?[​](#what-is-koreader "Direct link to What is KOReader?")

[KOReader](https://koreader.rocks/) is a free, open-source document viewer for E Ink and Android devices, popular on Kobo, Kindle, PocketBook, reMarkable, and many other eReaders. The BookFusion plugin brings your cloud library straight into KOReader, so you can download books and sync your reading data without any manual file transfers.

Ready to install?

Jump straight to the **[plugin setup guide](https://docs.bookfusion.com/docs/KOReader/koreader-install-plugin)** — it takes only a few minutes to copy the plugin across and link your device.

## How It Works[​](#how-it-works "Direct link to How It Works")

```
Your BookFusion Library  →  KOReader Plugin  →  BookFusion Cloud  →  All Your Devices
```

The plugin runs inside KOReader and connects to your BookFusion account through a one-time device link. Once linked, you can browse and download books, and your reading position and highlights flow two ways — between every KOReader device and the BookFusion apps.
