+Ruby4Knime is a realization of special node types for http://knime.org that allow to use Ruby scripts for interactive data analytic.
+The main aims of this project are:
 * provide possibility to use Ruby language for interactive data analysis;
 * make the analysis more effective using clear and laconic Ruby style.
 
-knime.rb is the simple wrapper that allows to use Knime classes written in Java in the Ruby programming style.
+knime.rb is the simple mediator that allows to use KNIME`s classes written in Java in the Ruby programming style and also use all Java classes without any changes.
