+
+Calibre-Web is a web app providing a clean interface for browsing, reading and downloading eBooks using an existing [Calibre](https://calibre-ebook.com) database.
+
+*This software is a fork of [library](https://github.com/mutschler/calibreserver) and licensed under the GPL v3 License.*

+
+## Quick start
+
+1. Install dependencies by running `pip install --target vendor -r requirements.txt`.
+2. Execute the command: `python cps.py` (or `nohup python cps.py` - recommended if you want to exit the terminal window)
+3. Point your browser to `http://localhost:8083` or `http://localhost:8083/opds` for the OPDS catalog
+4. Set `Location of Calibre database` to the path of the folder where your Calibre library (metadata.db) lives, push "submit" button\
+   Optionally a Google Drive can be used to host the calibre library [-> Using Google Drive integration](https://github.com/janeczku/calibre-web/wiki/Configuration#using-google-drive-integration)
+5. Go to Login page
+
+**Default admin login:**\
+*Username:* admin\
+*Password:* admin123
+
+**Issues with Ubuntu:**
+Please note that running the above install command can fail on some versions of Ubuntu, saying `"can't combine user with prefix"`. This is a [known bug](https://github.com/pypa/pip/issues/3826) and can be remedied by using the command `pip install --system --target vendor -r requirements.txt` instead.
+
+## Requirements
+
+Python 2.7+, python 3.x+
+
+Optionally, to enable on-the-fly conversion from one ebook format to another when using the send-to-kindle feature, or during editing of ebooks metadata:
+
+[Download and install](https://calibre-ebook.com/download) the Calibre desktop program for your platform and enter the folder including program name (normally /opt/calibre/ebook-convert, or C:\Program Files\calibre\ebook-convert.exe) in the field "calibre's converter tool" on the setup page.
+
+\*** DEPRECATED \*** Support will be removed in future releases
+
+[Download](http://www.amazon.com/gp/feature.html?docId=1000765211) Amazon's KindleGen tool for your platform and place the binary named `kindlegen` in the `vendor` folder.
+
+## Docker Images
+
+Pre-built Docker images are available in these Docker Hub repositories:
+
+#### **Technosoft2000 - x64**
++ Docker Hub - [https://hub.docker.com/r/technosoft2000/calibre-web/](https://hub.docker.com/r/technosoft2000/calibre-web/)
++ Github - [https://github.com/Technosoft2000/docker-calibre-web](https://github.com/Technosoft2000/docker-calibre-web) 
+
+    Includes the Calibre `ebook-convert` binary.
+    + The "path to convertertool" should be set to `/opt/calibre/ebook-convert`
+
+#### **LinuxServer - x64, armhf, aarch64**
++ Docker Hub - [https://hub.docker.com/r/linuxserver/calibre-web/](https://hub.docker.com/r/linuxserver/calibre-web/)
++ Github - [https://github.com/linuxserver/docker-calibre-web](https://github.com/linuxserver/docker-calibre-web)
++ Github - (Optional Calibre layer) - [https://github.com/linuxserver/docker-calibre-web/tree/calibre](https://github.com/linuxserver/docker-calibre-web/tree/calibre) 
+
+   This image has the option to pull in an extra docker manifest layer to include the Calibre `ebook-convert` binary.  Just include the environmental variable `DOCKER_MODS=linuxserver/calibre-web:calibre` in your docker run/docker compose file. **(x64 only)**
+  
+   If you do not need this functionality then this can be omitted, keeping the image as lightweight as possible.
+    
+   Both the Calibre-Web and Calibre-Mod images are rebuilt automatically on new releases of Calibre-Web and Calibre respectively, and on updates to any included base image packages on a weekly basis if required.
+   + The "path to convertertool" should be set to `/usr/bin/ebook-convert`
+   + The "path to unrar" should be set to `/usr/bin/unrar`
