 This setup takes advantage of the Nix package manager, which handles downloading and compiling everything. You must first install it on your Linux host PC if it doesn't run NixOS. Most distros are compatible, and installation (and uninstallation) is simple. Instructions are available on the [NixOS website](https://nixos.org/download.html#nix-quick-install).
 
-If you cannot or do not wish to install Nix and/or build these components yourself, installation ISOs are automatically built and made available from the [GitHub Releases page](https://github.com/tpwrules/nixos-m1/releases). Use `dd` or similar to transfer it to your USB flash drive. Programs like `unetbootin` are not supported. They are fully reproducible; that is, the ISO you download will be (or should be...) bit-identical to the one you will get by following these preparation instructions.
