Some (perhaps most) services assume that you are somewhat familiar with the software in question. For example, the explanation of the openssh-configuration in the Guix manual explains what the configuration items do, but if you don't know what OpenSSH is, then it probably doesn't help you very much. When you encounter situations like this, you might sometimes need to read more about the software in question before you will understand how to use it in GuixSD. This is generally true for any GNU/Linux distribution. > I started to learn guile at free time.

In cases like this, your best bet is to do the following: 1) Check the GNU Guix manual. You can read it online [1] or on your computer via the command "info guix". 2) Check the GNU Guix source. It sounds like you already know how to do that. Sometimes, the source code contains helpful information that has not yet been added to the manual. 3) Search the help-guix@gnu.org email archives [2] for information. Sometimes, the same question has been asked before. It's also useful to search the guix-devel@gnu.org email list [3], since a lot of discussion happens there, also. 4) If you still don't understand something, ask for help at help-guix@gnu.org. You can also ask for help in our IRC chat room [4]. Nobody starts out knowing everything. The Guix community is very welcoming to newcomers, and I'm sure that if you take the time to ask questions, you'll receive friendly, useful advice. Good luck!
