## 2. Connecting E-Readers (OPDS & KoSync)

Calibre-Web supports **OPDS** (Open Publication Distribution System) for browsing and downloading books directly on e-readers, as well as **KoSync** for syncing your reading progress and bookmarks across multiple devices.

> [!WARNING]
> **Application Key Required for E-Readers**
> Standard passkeys and Single Sign-On do **not** work directly inside third-party e-reader apps. To connect an e-reader app, you must generate a dedicated **Application Key**:
> 
> 1. Log in to [rookery.mynest.love](https://rookery.mynest.love) in your web browser.
> 2. Open your **Account Settings**.
> 3. Under **Application Keys**, enter a label (e.g., *"KOReader Kobo"* or *"Readest iPhone"*) and click **Generate**.
> 4. **Copy the key immediately!** It will only be displayed once. (We recommend saving it in **Vaultwarden**[cite: 5, 7]).

### E-Reader Endpoints & Login Credentials
When logging in from an e-reader app, use the following credentials:
* **Username:** Your Nest username

## 3. Recommended E-Reader Clients

You can connect any app that supports OPDS or KoSync. Here are our top recommended e-reader applications:

* **[KOReader](https://koreader.rocks/):** *(Available for Android, Kindle, Kobo, Windows, Linux)* — The premier open-source reading application featuring native OPDS browsing and built-in KoSync support.
* **[Readest](https://readest.app/):** *(Available for iOS)* — A sleek, modern e-reader app for iPhone and iPad with built-in OPDS support.

> [!TIP]
> **Have a Kindle?**
> If you'd like to install KOReader on a Kindle, check out [Kindle Mod Shelf](https://kindlemodshelf.me/) for jailbreaking guides! Alternatively, you can use the web interface's *"Send to Kindle"* feature to deliver EPUB or MOBI files directly to your Amazon account.

## 4. Where Does Content Come From?

To keep metadata, covers, and series details clean and consistent, direct file uploads inside Calibre-Web are disabled.

* **Requesting New Books:** Request any e-book title via **[Shelfmark](../media-request/shelfmark.md)**! Shelfmark automatically fetches high-quality metadata and imports the book directly into Calibre-Web.
* **Contributing Existing Libraries:** Have a large collection of e-books you'd like to share with The Nest? Reach out to an administrator on Matrix to arrange a batch import!

## 5. Hardcover Reading Tracker Integration

2. Generate an **API Token** in your Hardcover account settings.
3. Paste the token into your Calibre-Web account settings on [rookery.mynest.love](https://rookery.mynest.love).
