Install a Windows image
-----------------------
1. Adjust demo-image.nix accordingly
1. Adjust demo-image in ``flake.nix`` accordingly
2. Run:
If in impure mode
```shell
nix-build demo-image.nix
nix build .#demo-image
./result
```
Results in a file called c.img
If in pure mode
```shell
nix-build demo-image.nix
ls -la ./result
```
Results in a symlink to the image in the nix store
@ -52,3 +45,5 @@ Impure/pure mode
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.
When building an image with flakes, use ``nix build .#demo-image-impure`` instead.
