+This project spins up a Clojure project within a Docker image.
+
+The Docker image exposes a SSH server.
+
+This way, for development purposes, we can SSH into it with TRAMP and exercise
CIDER's TRAMP-related capabilities.
+
+To get started:
+
+* In one terminal tab, run `make run` to run the Docker image
+* Once it's ready, from another tab, run `make ssh`
+ * The password is `cider`
+ * `cd /usr/src/app; lein repl :headless :host 0.0.0.0 :port 7888`
+
+Now, from emacs you can `cider-connect` to localhost.
+
+* `M-:`, `(dired "/sshx:root@localhost#8022:/usr/src/app")`
+* `M-x cider-connect` (choose `localhost`, `7888`)
