+First, obtain the projects guix channel file. There are two ways to do this; with http
+fetching only the channel file, or with git, fetching the entire dotfiles project; the later
+is necessary if you plan on [[*Working with Local Sources][Working with Local Sources]].

+Then, use guix to pull the provided channel file and reconfigure guix-home.

+prerequisite being guix itself.
