 *** Usage
-Currently you have to have =eclimd= already started.
-This layer doesn't try to control =eclimd= in no way although there's that
-option in =emacs-eclim= itself.
+To start the eclimd daemon, you can either invoke via =SPC m d s= (or whatever
+you've bound it to) or via =start-eclimd=. The process blocks for a while.
+
+To stop the daemon, you can either invoke via =SPC m d k= or =stop-eclimd=.
