+## Installing statsample development dependencies
+
+Keep in mind that either nmatrix OR rb-gsl are NOT NECESSARY for using statsample. They are just required for an optional speed up. 
+
+Statsample also works with [rb-gsl](https://github.com/sciruby/rb-gsl).
+
+Install dependencies:
+
+  `bundle install`
+
+And run the test suite (should be all green):
+
+  `bundle exec rake test`
+
+If you have problems installing nmatrix, please consult the [nmatrix installation wiki](https://github.com/SciRuby/nmatrix/wiki/Installation) or the [mailing list](https://groups.google.com/forum/#!forum/sciruby-dev).
