+Original prototype, last modified 2015-03-14
+
+First install [Racket](http://racket-lang.org) (just for the initial
+prototype). Then:
+
+  ```shell
+  $ cd mu/arc
+  $ git clone http://github.com/arclanguage/anarki
+  $ ./mu test mu.arc.t  # run tests
+  ```
+
+Example programs:
+
+  ```shell
+  $ ./mu factorial.mu  # computes factorial of 5
+  $ ./mu fork.mu  # two threads print '33' and '34' forever
+  $ ./mu channel.mu  # two threads in a producer/consumer relationship
+  ```
