+To create a channel, create a Git repository containing your own package

+channel's Git repository has been added to the Guile load path (@pxref{Load
+Paths,,, guile, GNU Guile Reference Manual}). For example, if your channel
+contains a file at @file{my-packages/my-tools.scm} that defines a Guile
+module, then the module will be available under the name @code{(my-packages
+my-tools)}, and you will be able to use it like any other module
