 #### Uninstall PaperWM (if installed via source)
+
 To uninstall simply run `./uninstall.sh`.
 
 Running the extension will automatically install a user config file as described in [User configuration & development](#user-configuration--development).
 
+
+### Try without installing
+
+This repo provides a lightweight VM based on [NixOS](https://nixos.org) to try PaperWM and aid with development. You can launch it if [Nix](https://nixos.org/nix) is installed on your system using this command:
+
+```sh
+nix run .\#vm
+```
+
+Alternatively, the VM can also be launched with GPU acceleration, by installing [NixGL](https://github.com/nix-community/nixgl) first:
+
+```sh
+nixGLIntel nix run .\#vm -- -device virtio-gpu-gl -display gtk,gl=on
+# or nixGLNvidia depending on your host GPU
+```
+
