debian-guix-installer/README.md

To install Guix on Debian-based systems execute the following commands:

$ git clone https://notabug.org/isengaara/debian-guix-installer.git
$ cd debian-guix-installer
$ make
$ sudo dpkg -i guix-installer.deb
$ sudo /gnu/guix_installer/setup

You can test if it works installing the hello package:

$ guix package -i hello
$ export PATH="/home/$USER/.guix-profile/bin${PATH:+:}$PATH"
$ hello

You should get the "Hello, world!" message or its equivalent in your locale.
