python3 -m venv calibre-web-env
```
2. **Activate the virtual environment**:
```
source calibre-web-env/bin/activate
```
3. **Install Calibre-Web**: Use pip to install the application:
```
pip install calibreweb
```
4. **Install optional features**: For additional functionality, you may need to install optional features. Refer to [this page](https://github.com/janeczku/calibre-web/wiki/Dependencies-in-Calibre-Web-Linux-and-Windows) for details on what can be installed.

```
### Important Links
- For additional installation examples, check the following:
- [Manual installation](https://github.com/janeczku/calibre-web/wiki/Manual-installation)
- [Linux Mint installation](https://github.com/janeczku/calibre-web/wiki/How-To:-Install-Calibre-Web-in-Linux-Mint-19-or-20)
- [Cloud Provider setup](https://github.com/janeczku/calibre-web/wiki/How-To:-Install-Calibre-Web-on-a-Cloud-Provider)
## Quick Start
1. **Access Calibre-Web**: Open your browser and navigate to:
```
http://localhost:8083
```
or for the OPDS catalog:
```
http://localhost:8083/opds
```
2. **Log in**: Use the default admin credentials:
- **Username:** admin
- **Password:** admin123
3. **Database Setup**: If you do not have a Calibre database, download a sample from:
```
https://github.com/janeczku/calibre-web/raw/master/library/metadata.db
```
Move it out of the Calibre-Web folder to avoid overwriting during updates.
4. **Configure Calibre Database**: In the admin interface, set the `Location of Calibre database` to the path of the folder containing your Calibre library (where `metadata.db` is located) and click "Save".
5. **Google Drive Integration**: For hosting your Calibre library on Google Drive, refer to the [Google Drive integration guide](https://github.com/janeczku/calibre-web/wiki/G-Drive-Setup#using-google-drive-integration).
6. **Admin Configuration**: Configure your instance via the admin page, referring to the [Basic Configuration](https://github.com/janeczku/calibre-web/wiki/Configuration#basic-configuration) and [UI Configuration](https://github.com/janeczku/calibre-web/wiki/Configuration#ui-configuration) guides.
## Requirements
- **Python Version**: Ensure you have Python 3.7 or newer.
- **Imagemagick**: Required for cover extraction from EPUBs. Windows users may also need to install [Ghostscript](https://ghostscript.com/releases/gsdnld.html) for PDF cover extraction.
- **Windows Users**: Install [libmagic](https://gnuwin32.sourceforge.net/downlinks/file.php) for 32bit python or [libmagic for 64bit python](https://github.com/nscaife/file-windows/releases/tag/20170108), depending on your Python version. Make sure these files are included in your path.
- **Optional Tools**:
- **Calibre desktop program**: Recommended for on-the-fly conversion and metadata editing. Set the path to Calibres converter tool on the setup page.
- **Kepubify tool**: Needed for Kobo device support. Download the tool and place the binary in `/opt/kepubify` on Linux or `C:\Program Files\kepubify` on Windows.
## Docker Images
Pre-built Docker images are available:
### **LinuxServer - x64, aarch64**
- **Docker Hub**: [linuxserver/calibre-web](https://hub.docker.com/r/linuxserver/calibre-web)

- **Optional Calibre layer**: [linuxserver/docker-mods](https://github.com/linuxserver/docker-mods/tree/universal-calibre)
To include the Calibre `ebook-convert` binary (x64 only), add the environment variable:
```
DOCKER_MODS=linuxserver/mods:universal-calibre
```
in your Docker run/compose file. Omit this variable for a lightweight image.

## Troubleshooting
- **Common Issues**:
- If you experience issues starting the application, check the log files located in the `logs` directory for error messages.
- If eBooks fail to load, verify that the `Location of Calibre database` is correctly set and that the database file is accessible.
- **Configuration Errors**: Ensure that your Calibre database is compatible and properly formatted. Refer to the Calibre documentation for guidance on maintaining the database.
- **Performance Problems**:
- If the application is slow, consider increasing the allocated resources (CPU/RAM) to your server or optimizing the Calibre database by removing duplicates and unnecessary entries.
- Regularly clear the cache in your web browser to improve loading times.
- **User Management Issues**: If users are unable to log in or register, check the user permission settings in the admin interface. Ensure that registration is enabled and that users are being assigned appropriate roles.
- **Support Resources**: For additional help, consider visiting the [FAQ section](https://github.com/janeczku/calibre-web/wiki/FAQ) of the wiki or posting your questions in the [Discord community](https://discord.gg/h2VsJ2NEfB).
