It’s a fine first book. I’d certainly recommend it. I don’t recall if it has instructions on getting a dev env up and running, but if it does I imagine they’re out of date. Emacs with Sly or SLIME is what I’ve used, but I believe there are viable options for proper interactive development in vim and vs code among others. If you just use a basic editor and paste code into a repl in a terminal you won’t be getting the experience most Lispers do.
