 By default all those variables are set to strings (e.g. `lein repl`).
 However, it is possible to use a cons pair like `("localhost" . 5555)`

+#### Lumo Socket REPL
+
+For lumo, setup a generic command in `init.el` to start the socket repl (say, port 5555)
+
+```el
+(setq inf-clojure-repl-use-same-window nil)
+(setq inf-clojure-generic-cmd '("localhost" 5555))

+Then start lumo repl, like so:

+```
+
+If you want to use lumo with Clojure devtools
+[dependencies](https://clojure.org/guides/deps_and_cli) without lein or boot,
+add a `deps.edn` in the project root and run this command:
+
+```bash
+lumo -c `clj -Spath` -n 5555
+```
+
+You can use `M-x inf-clojure-connect` (`C-c M-c`) to connect to a running
+socket-repl. You will be prompted for host and port.
