 # Introduction
 
-Quickemu is a simple script to *"manage"* Qemu virtual machines. Each virtual
-machine configuration is a few lines long requiring minimal setup. The
-main objective of the project is to enable quick testing of desktop Linux
-distributions where the virtual machines configuration and disk images can be
-stored anywhere, such as external USB storage or your home directory. **Windows
-and macOS guests are also supported.**
+Quickemu quickly creates and runs highly optimised desktop virtual machines for
+Linux, macOS and Windows; in just with just two commands. You decide what
+operating system you want to run and Quickemu will figure out the best way to
+do it for you. For example:
 
-Quickemu will attempt to *"do the right thing"* rather than expose rich
-configuration options. Quickemu is a wrapper for [QEMU](https://www.qemu.org/).
-See the video where I explain some of my motivations for creating this script.
+```bash
+quickget ubuntu-mate hirsute
+quickemu --vm ubuntu-mate-hirsute.conf
+```
+
+The original objective of the project was to enable quick testing of Linux
+distributions where the virtual machine configurations can be stored anywhere,
+such as external USB storage or your home directory, and no elevated permissions
+are required to run the virtual machines. **Quickemu now also includes
+comprehensive support for macOS and Windows**.
+
+## Features

+  * VirtIO-webdavd file sharing for Linux and Windows guests.
+  * VirtIO-9p file sharing for Linux and macOS guests.
+  * VirGL acceleration
+  * USB device pass-through
+  * Smartcard pass-through

+  * Network port forwarding
+  * EFI and Legacy BIOS booting
+
+Quickemu is a wrapper for the excellent [QEMU](https://www.qemu.org/) that
+attempts to automatically *"do the right thing"*, rather than expose exhaustive
+configuration options.
