2. How to Run KOReader on E-ink Devices

First-time users need to setup KOReader based on the device brand. Let's take PocketBook Reader as an example. Pocketbooks run a Linux-based operating system, so they can’t install Android apps, but they can install a few apps that work alongside the built-in reading software, including KOReader.

Step 1Download a Pocketbook version of KOReader from KOReader latest releases page here. Make sure to download a version labeled koreader-pocketbook.

Step 2Plug the Pocketbook ereader into a computer with the USB cable and select PC Link mode on the Pocketbook.

Step 3Unzip the KoReader archive on your computer. There will be two directories in the unzipped directory, namely applications and system.

Then transfer the applications directory to the applications folder to your PocketBook's USB storage.

If you want to associate KOReader with all PDF, EPUB, DJVU, FB2, CBZ documents, you need to copy and merge the system directory from the unzipped content to your PocketBook's USB storage as well. (This step is optional.)

Step 4Safely eject the Pocketbook from your computer and restart the device. Now you can access KOReader from the app section on the Pocketbook.

I have a kobo device. Unfortunately, it can no longer transfer via usb. So I have to download the books from the internet. Unfortunately, when I connect it to the computer, it does not see the computer. Can you tell me how to send a book to kobo online?
