Because of a bug in guix, the `guix home` command will not be found immediately:
106+
the search for the command is done too early, before guix adds the channels
107+
to its search path.  Add them to the guile search path, so guix will be able to
108+
find them.  Note that if you are running bash, the home manager will take
109+
care of that after you install the first generation:
110+
111+
```bash
112+
export GUILE_LOAD_PATH=~/.config/guix/current/share/guile/site/3.0:$GUILE_LOAD_PATH
113+
export GUILE_LOAD_COMPILED_PATH=~/.config/guix/current/lib/guile/3.0/site-ccache:$GUILE_LOAD_COMPILED_PATH
114+
```
