-The :hooks entry will enable clj-stacktrace to be used by clojure.test
-and other things that use the clojure.stacktrace library. The
-:repl-options entry will cause clj-stacktrace to be used in the
-repl. Colorized stacktraces in clojure.test can interfere with some
-tools like Swank, so by default it uses pst rather than pst+; you can
-change this with {:color true}.
+If you use Leiningen, you can install clj-stacktrace on a per-user basis:
+
+    $ lein plugin install clj-stacktrace 0.2.3
+
+Add this to your `~/.lein/init.clj` file:
+
+    (require 'leiningen.hooks.clj-stacktrace-test)
+
+    (def settings {:repl-options [:init (require 'clj-stacktrace.repl)
+                                  :caught 'clj-stacktrace.repl/pst+]})
+
+The hook will enable clj-stacktrace to be used across all the projects
+you work on in clojure.test and other things that use the
+clojure.stacktrace library. The :repl-options settings will cause
+clj-stacktrace to be used in the repl and swank.
