InkBox is an open-source, Qt-based eBook reader for Kobo devices. It also comes as an entire [native open-source OS](https://github.com/Kobo-InkBox/rootfs) and provides support for a number of devices.
- Strict security policy ensuring that only signed software can be run on the device (this, however, can be adapted to your needs by recompiling the [kernel](https://github.com/Kobo-InkBox/kernel))
You can download precompiled OS/binaries [here](http://23.163.0.39/bundles/inkbox/native/) and standard Nickel add-ons (outdated, unmaintained) are available [here](http://23.163.0.39/bundles/inkbox/nickel/), although support for them has been stopped until further notice. Huge thanks to [@fermino](https://github.com/fermino) for providing free hosting.
On Linux and MacOS, [balenaEtcher](https://www.balena.io/etcher/) is the easiest option for command-line-reluctant users.
Alternatively, you can also open a terminal and check the device node of the Kobo's SD card with `fdisk -l`. Then `dd` the image to the SD card like this:
To upgrade InkBox, go to http://23.163.0.39/bundles/inkbox/native/update/ and extract the files for your device onto the `.inkbox` folder in the USB storage partition.
*Note*: Prior to version 1.6, InkBox had to be upgraded one version at a time. If your device's factory image ships with version 1.5, you need to closely follow the upgrade instructions [here](http://23.163.0.39/bundles/inkbox/native/update/1.6/HOWTO-Update).
I suggest you visit the [wiki](http://inkbox.ddns.net:40/wiki). The [General information](http://inkbox.ddns.net:40/wiki/index.php?title=General_information) page is a pretty good place to start. Feel free to contribute if you think you have something valuable to add.
If you like this project and want to improve it in some way, feel free to fork this repository or [one of the subprojects this organization hosts](https://github.com/Kobo-InkBox), then make a [pull request](https://github.com/Kobo-InkBox/inkbox/pulls). I'll be happy to review it when I have time.
On the other hand, if you don't have the appropriate coding skills or just want to help in some way, feel free to make a donation at my [PayPal account](https://paypal.me/NicolasMailloux/) or on [LiberaPay](https://liberapay.com/tux-linux/). I'm a student and motivation has been the only thing that has helped me maintain this project for the last months. Developing an entire operating system on my own was not an easy task. I have time, but I like to spend it wisely.
