 A Nix library to create and manage virtual machines running Windows, a medieval operating system found on most computers in 2020. The F stands for "Functional" or a four-letter word of your choice.
 
 * Reproducible - everything runs in the Nix sandbox with no tricks.
-* Fully automatic, parameterizable Windows 10 installation.
+* Fully automatic, parameterizable Windows 11 installation.
 * Uses QEMU with KVM.
 * Supports incremental installation (using "layers") of additional software via QEMU copy-on-write backing chains. For example, ``wfvm.makeWindowsImage { installCommands = [ wfvm.layers.anaconda3 ]; };`` gives you a VM image with Anaconda3 installed, and ``wfvm.makeWindowsImage { installCommands = [ wfvm.layers.anaconda3 wfvm.layers.msys2 ]; };`` gives you one with both Anaconda3 and MSYS2 installed. The base Windows installation and the Anaconda3 data are shared between both images, and only the MSYS2 installation is performed when building the second image after the first one has been built.
 * Included layers: Anaconda3, a software installer chock full of bugs that pretends to be a package manager, Visual Studio, a spamming system for Microsoft accounts that includes a compiler, and MSYS2, which is the only sane component in the whole lot.

 Sometimes it can be useful to build the image _outside_ of the Nix sandbox for debugging purposes.
 
 For this purpose we have an attribute called `impureMode` which outputs the shell script used by Nix inside the sandbox to build the image.

+Usage with Nix Flakes
+---------------------
+
+Build the demo by running:
+```shell
+nix build .#demoImage
+```
+
+This project's **flake.nix** exposes its functions under `lib`. To use
+in your own project, setup your flake like this:
