# LeonOS ###### look, mom, a proper Markdown readme! LeonOS is a reimplementation of [CC: Tweaked](https://github.com/CC-Tweaked/CC-Tweaked)'s LeonOS, intended to be cleaner and easier than the original LeonOS. Key changes: - No. More. CCPL!! - All previously global APIs (with the exception of the standard Lua ones) have been removed. - Non-standard `os` API functions are now in the `rc` table, e.g. `os.sleep` becomes `rc.sleep` or `os.pullEvent` becomes `rc.pullEvent`. - Native support for proper thread management (`parallel` implementation builds on this) - Multishell works even on standard computers, and is navigable with keyboard shortcuts! See [the LeonOS website](https://ocaweso.me/LeonOS) for more details.
