-== Installing
+== Taking mu for a spin
+
 Prerequisites: Racket from http://racket-lang.org
 
-$ cd mu
-$ git clone http://github.com/arclanguage/anarki
+  $ cd mu
+  $ git clone http://github.com/arclanguage/anarki
+
+Now try a test program.
+
+  $ cat x.mu  # simple example to add two numbers
+  (main
+    ((x integer) <- copy (1 literal))
+    ((y integer) <- copy (3 literal))
+    ((z integer) <- add (x integer) (y integer))
+  )
+
+  $ ./anarki/arc mu.arc x.mu
+  #hash((1 . 1) (2 . 3) (3 . 4))  # state of simulated memory after executing x.mu
+
+Location z contains the sum of locations x and y.
+(You have to imagine that location 3 maps to 'z' for now, sorry..)
+
+== Now dive in
+
+Try running the tests:
+
+  $ ./anark/arc mu.arc.t
 
-$ ./anark/arc mu.arc.t  # automated tests; start reading here
-# mu.arc.t.html might be easier to read in your browser
+Now start reading mu.arc.t. The html rendering mu.arc.t.html might be easier
+to read in your browser.
