rakuyomi is a manga reader plugin for KOReader.

"Ubunchu!" by Hiroshi Seo is licensed under CC BY-NC 3.0.

Download the latest release for your device from the releases page. Currently, only Kindle devices are supported (the Kindle build should work with Kobo devices, but it's untested).

Place the rakuyomi.koplugin folder inside KOReader's plugins folder.

In order to use the plugin, you'll need to add some sources. rakuyomi is compatible with Aidoku sources. The easiest way to obtain sources is to configure source lists and download the sources through the app.

You'll most likely find links with the format https://aidoku.app/add-source-list/?url=<source list URL>. Grab the source list URL from these links and make sure it ends with /index.min.json. If it doesn't, add it yourself.

Create a rakuyomi/settings.json file inside KOReader's home directory, with the following contents:

{
    "$schema": "https://github.com/hanatsumi/rakuyomi/releases/download/main/settings.schema.json",
    "source_lists": [
        "https://samplewebsite.com/sources/index.min.json",
        "<your source list URL>"
    ],
    "languages": ["en", "<your preferred language here>"]
}

After configuring a source list, sources can be installed through the plugin, by going to the main menu and going to "Manage sources".

For a better manga reading experience, you might also look into KOReader's reader recommended settings.

In KOReader's file manager, go to the "Search" menu and tap on the "Rakuyomi" entry to open the library view. Tap the menu button on the top left to open the main menu.
