In the tutorial below, I show how to download a KOReader One-click package and an install script for Mac, and then install KOReader on my Kobo Libra H2O. KOReader is a ebook launcher / UI for E Ink devices. Supported file formats include EPUB, PDF, DjVu, XPS, CBT, CBZ, FB2, PDB, TXT, HTML, RTF, CHM, DOC, MOBI and ZIP files. It’s available for Kindle, Kobo, PocketBook, Android and desktop Linux. Works great. It makes your e-reader really snappy and fast, and it adds a lot more features than it originally has.
