86Box
=====
[![Build Status](https://ci.86box.net/job/86Box/badge/icon)](https://ci.86box.net/job/86Box/)
**86Box** is a low level x86 emulator that runs older operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus.
Features
--------
* Easy to use interface inspired by mainstream hypervisor software
* Low level emulation of 8086-based processors up to the Mendocino-era Celeron with focus on accuracy
* Great range of customizability of virtual machines

* Windows version: Windows 7 Service Pack 1 or later
* Linux version: Ubuntu 16.04, Debian 9.0 or other distributions from 2016 onwards
@@ -25,6 +28,7 @@ Minimum system requirements and recommendations
Performance may vary depending on both host and guest configuration. Most emulation logic is executed in a single thread; therefore, systems with better IPC (instructions per clock) generally should be able to emulate higher clock speeds.
It is also recommended to use a manager application with 86Box for easier handling of multiple virtual machines.

Getting started
---------------
See [our documentation](https://86box.readthedocs.io/en/latest/index.html) for an overview of the emulator's features and user interface.
Community
---------
We operate an IRC channel and a Discord server for discussing 86Box, its development and anything related to retro computing. We look forward to hearing from you!
