-# Inf Clojure
+# inf-clojure
 
 This package provides basic interaction with a Clojure subprocess (REPL).
+It's based on ideas from the popular `inferior-lisp` package.
+
+`inf-clojure` has two components - a nice Clojure REPL with
+auto-completion and a minor mode (`inf-clojure-minor-mode`), which
+extends `clojure-mode` with commands to evaluate forms directly in the
+REPL.
