| General topics
LibreELEC (short for "Libre Embedded Linux Entertainment Center") is small and very fast booting, open source JeOS (Just enough Operating System). LibreELEC is a complete media center software suite for embedded systems and computers, as it comes with a pre-configured version of Kodi and optional third-party PVR backend software.
LibreELEC works on most computers and you can install Kodi on the Raspberry Pi as well as a few other selected single-board computers and media player devices. LibreELEC is, like OpenELEC, also optimized to be used with flash based drives, like compact flash, USB drives, or SSD harddrives.
This fork of OpenELEC was announced in March of 2016 as a split from the OpenELEC team after "creative differences", taking with it a number of active developers at the time which joined the new LibreELEC project.
