 ;; tuareg is the preferred ocaml mode for Emacs
 
+;; These setups for ocaml assume that you are using the OPAM package
+;; manager (http://opam.ocaml.org/).
+
+;; Because of the apparent complexity of getting emacs environment
+;; variables setup to use opam correctly, it is instead easier to use
+;; opam itself to execute any necessary commands.
+
+;; Also, the standard OCaml toplevel usage has been replaced in favor
+;; of UTOP, the universal toplevel, and we assume that you are using
+;; the Jane Street Core libraries rather than the regular OCaml
+;; standard libraries
+
+;; The minimum required setup for using Prelude's OCaml setup would be
+;; to install OPAM, and then, minimally `opam install core utop'.  A
+;; good getting started guide is available at
+;; https://github.com/realworldocaml/book/wiki/Installation-Instructions
