+# HotRuby
+
+HotRuby is a Ruby VM build with JavaScript and Flash, that runs opcode compiled by Ruby 1.9+
+
+Most of the grammars are implemented. However, exceptions are not implemented. Most of the build-in functions and build-in classes are not implemented.
+
+# Running it
+
+ rake build
+ cd web
+ rackup
+
+# Github?
+
+It was developed by yukoba ? [official website](http://hotruby.accelart.jp)
+
+[original repository](http://code.google.com/p/hotruby) seems to be abandoned.
+
+Github to the rescue!
