I’m not too familiar with Kit, but I think deps.edn is the right choice here.

Thank you. Now it asks me: • build • cider Has main-opts. Only select this alias if it starts an REPL_sever • dev • nrepl Has main opts. Only select this alias if it starts an REPL server. • test Has main opts. Only select this alias if it starts an nREPL sever. Which should I select?

Probably dev. Let me check … yes, dev is what they use here: https://kit-clj.github.io/docs/guestbook.html#starting_our_server

Thank you, it works.
