+## How to contribute to Calibre-Web
+
+First of all, we would like to thank you for reading this text. we are happy you are willing to contribute to Calibre-Web
+
+### **General**
+
+**Communication language** is english. Google translated texts are not as bad as you might think, they are usually understandable, so don't worry if you generate your post that way.
+
+**Calibre-Web** is not **Calibre**. If you are having a question regarding Calibre please post this at their [repository](https://github.com/kovidgoyal/calibre).
+
+**Docker-Containers** of Calibre-Web are maintained by different persons than the people who drive Calibre-Web. If we come to the conclusion during our analysis that the problem is related to Docker, we might ask you to open a new issue at the reprository of the Docker Container.
+
+If you are having **Basic Installation Problems** with python or it's dependencies, please consider using your favorite search engine to find a solution. In case you can't find a solution, we are happy to help you.
+
+We can offer only very limited support regarding configuration of **Reverse-Proxy Installations**, **OPDS-Reader** or other programs in combination with Calibre-Web. 
+
+### **Translation**
+
+Some of the user languages in Calibre-Web having missing translations. We are happy to add the missing texts if you translate them. Create a Pull Request, create an issue with the .po file attached, or write an email to "ozzie.fernandez.isaacs@googlemail.com" with attached translation file. To display all book languages in your native language an additional file is used (iso_language_names.py). The content of this file is autogenerated with the corresponding translations of Calibre, please do not edit this file on your own. 
+
+### **Documentation**
+
+The Calibre-Web documentation is hosted in the Github [Wiki](https://github.com/janeczku/calibre-web/wiki). The Wiki is open to everybody, if you find a problem, feel free to correct it. If information is missing, you are welcome to add it. The content will be reviewed time by time. Please try to be consitent with the form with the other Wiki pages (e.g. the project name is Calibre-Web with 2 capital letters and a dash in between).
+
+### **Reporting a bug**
+
+Do not open up a GitHub issue if the bug is a **security vulnerability** in Calibre-Web. Please write intead an email to "ozzie.fernandez.isaacs@googlemail.com".
+
+Ensure the ***bug was not already reported** by searching on GitHub under [Issues](https://github.com/janeczku/calibre-web/issues). Please also check if a solution for your problem can be found in the [wiki](https://github.com/janeczku/calibre-web/wiki).
+
+If you're unable to find an **open issue** addressing the problem, open a [new one](https://github.com/janeczku/calibre-web/issues/new?assignees=&labels=&template=bug_report.md&title=). Be sure to include a **title** and **clear description**, as much relevant information as possible, the **issue form** helps you providing the right information. Deleting the form and just pasting the stack trace doesn't speed up fixing the problem. If your issue could be resolved, consider closing the issue. 
+
+### **Feature Request**
+
+If there is a feature missing in Calibre-Web and you can't find a feature request in the [Issues](https://github.com/janeczku/calibre-web/issues) section, you could create a [feature request](https://github.com/janeczku/calibre-web/issues/new?assignees=&labels=&template=feature_request.md&title=). 
+We will not extend Calibre-Web with any more login abilitys or add further files storages, or file syncing ability. Furthermore Calibre-Web is made for home usage for company inhouse usage, so requests regarding any sorts of social interaction capability, payment routines, search engine or web site analytics integration will not be implemeted. 
+
+### **Contributing code to Calibre-Web**
+
+Open a new GitHub pull request with the patch. Ensure the PR description clearly describes the problem and solution. Include the relevant issue number if applicable.
+
+In case your code enhances features of Calibre-Web: Create your pull request for the development branch if your enhancement consits of more than some lines of code in a local section of Calibre-Webs code. This makes it easier to test it and check all implication before it's made public. 
+
+Please check if your code runs on Python 2.7 (still necessary in 2020) and mainly on python 3. If possible and the feature is related to operating system functions, try to check it on Windows and Linux. 
+Calibre-Web is automatically tested on Linux in combination with python 3.7. The code for testing is in a [seperate repo](https://github.com/OzzieIsaacs/calibre-web-test) on Github. It uses unittest and performs real system tests with selenium, would be great if you could consider also writing some tests. 
+A static code analysis is done by Codacy, but it's partly broken and doesn't run automatically. You could check your code with ESLint before contributing, a configuration file can be found in the projects root folder.

+## Quick start
+
+1. Install dependencies by running `pip3 install --target vendor -r requirements.txt` (python3.x) or `pip install --target vendor -r requirements.txt` (python2.7).
+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 3.x+, (Python 2.7+)
+
+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.
+
+[Download](https://github.com/geek1011/kepubify/releases/tag/v3.1.2) Kepubify tool for your platform and place the binary starting with `kepubify` in Linux: `\opt\kepubify` Windows: `C:\Program Files\kepubify`.
+
+## 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`

+"""This module is used to control authentication/authorization of Kobo sync requests.
+This module also includes research notes into the auth protocol used by Kobo devices.
+
+Log-in:
+When first booting a Kobo device the user must sign into a Kobo (or affiliate) account.
+Upon successful sign-in, the user is redirected to
+    https://auth.kobobooks.com/CrossDomainSignIn?id=<some id>
+which serves the following response:
+    <script type='text/javascript'>
+        location.href='kobo://UserAuthenticated?userId=<redacted>&userKey<redacted>&email=<redacted>&returnUrl=https%3a%2f%2fwww.kobo.com';
+    </script>
+And triggers the insertion of a userKey into the device's User table.
+
+Together, the device's DeviceId and UserKey act as an *irrevocable* authentication
+token to most (if not all) Kobo APIs. In fact, in most cases only the UserKey is
+required to authorize the API call.
+
+Changing Kobo password *does not* invalidate user keys! This is apparently a known
+issue for a few years now https://www.mobileread.com/forums/showpost.php?p=3476851&postcount=13
+(although this poster hypothesised that Kobo could blacklist a DeviceId, many endpoints
+will still grant access given the userkey.)
+
+Official Kobo Store Api authorization:
+* For most of the endpoints we care about (sync, metadata, tags, etc), the userKey is
+passed in the x-kobo-userkey header, and is sufficient to authorize the API call.
+* Some endpoints (e.g: AnnotationService) instead make use of Bearer tokens pass through
+an authorization header. To get a BearerToken, the device makes a POST request to the
+v1/auth/device endpoint with the secret UserKey and the device's DeviceId.
+* The book download endpoint passes an auth token as a URL param instead of a header.
+
+Our implementation:
+We pretty much ignore all of the above. To authenticate the user, we generate a random
+and unique token that they append to the CalibreWeb Url when setting up the api_store
+setting on the device.
+Thus, every request from the device to the api_store will hit CalibreWeb with the
+auth_token in the url (e.g: https://mylibrary.com/<auth_token>/v1/library/sync).
+In addition, once authenticated we also set the login cookie on the response that will
+be sent back for the duration of the session to authorize subsequent API calls (in
+particular calls to non-Kobo specific endpoints such as the CalibreWeb book download).
