Note that I'm assuming SBCL in this tutorial. If you use something else, it might or it might not work. Particularly daemonization is only supported in SBCL through sb-daemon (required if SBCL is detected).
I'm assuming you have Quicklisp installed. If you don't, I suggest you to drop everything and install Quicklisp. [Note: at the time I'm writing this, Sytes is not yet published therefore it can't possibly be available via Quicklisp, but I'll submit it as soon as possible].
Sytes depends on a few Common Lisp libraries; all of them are installable via Quicklisp, except (for now) sb-daemon. The easy way to install sb-daemon right now is:
mkdir -p ~/.local/share/common-lisp/source cd ~/.local/share/common-lisp/source/ git clone https://github.com/nikodemus/sb-daemon.git
Speaking of which, you can easily install Sytes in the same manner until it'll be available on Quicklisp—just clone the repository in ~/.local/share/common-lisp/source/.
Now try to load Sytes in your REPL:
CL-USER> (ql:quickload "sytes")
The above will install/load any additional dependencies via
I ♥ Quicklisp.
