-# Running Ruby from Clojure

 This is a simple example of calling Ruby from Clojure. It contains a simple
 JRuby project and a Clojure project:
 
-* steel_city - a Ruby project that returns the speakers for the given day
+* `steel_city` - a Ruby project that returns the speakers for the given day

-* speaker_selector - Returns a "top" speaker for the given day using a 
+* `speaker_selector` - Returns a "top" speaker for the given day using a 
   sophisticated algorithm (ie, random selection)
 
-## Compiling
-
-    cd steel_city
-    jrubyc --javac schedule.rb
-    jar -cf schedule.jar com/steelcity/Schedule.class
-
-## Installing with mvn
-
-In your clojure project, set up the dependencies in the project.clj. 
-You will need dependencies on jruby and your compiled jar.
-
-You will have to install these with mvn so that lein deps loads the
-dependencies:
+## Running
 
-    mvn install:install-file -DgroupId=com.steelcity.schedule \
-    	-DartifactId=com.steelcity.schedule -Dversion=0.0.0 \
-	-Dpackaging=jar -Dfile=schedule.jar
+    $ rake
 
-The command to install jruby to your local mvn repository will be similar.
+    => (import com.steelcity.Schedule)
+    => (top-speaker "Friday")
+    => (top-speaker "Saturday")
 
-## Running
+## How does this work?
 
-In the Clojure REPL, load the speaker-selector.core namespace and run:
