+
+Rubytree is a simple implementation of the generic Tree data structure.  This
+implementation is node-centric, where the individual nodes on the tree are the
+primary objects and drive the structure.
+
+== INSTALL:
+
+Rubytree is an open source project and is hosted at:
+
+   http://rubytree.rubyforge.org
+
+Rubytree can be downloaded as a Rubygem or as a tar/zip file from:
+
+   http://rubyforge.org/frs/?group_id=1215&release_id=8817
+
+The file-name is one of:
+
+    rubytree-<VERSION>.gem - The Rubygem
+    rubytree-<VERSION>.tgz - GZipped source files
+    rubytree-<VERSION>.zip - Zipped  source files
+
+Download the appropriate file-type for your system.
+
+It is recommended to install Rubytree as a Ruby Gem, as this is an easy way to
+keep the version updated, and keep multiple versions of the library available on
+your system.
+
+=== Installing the Gem
+
+To Install the Gem, from a Terminal/CLI command prompt, issue the command:
+
+   gem install rubytree
+
+This should install the gem file for Rubytree. Note that you may need to be a
+super-user (root) to successfully install the gem.
+
+=== Installing from the tgz/zip file
+
+Extract the archive file (tgz or zip) and run the following command from the
+top-level source directory:
+
+    ruby ./setup.rb
+
+You may need administrator/super-user privileges to complete the setup using
+this method.
+
+== DOCUMENTATION:
+
+The primary class for this implementation is Tree::TreeNode. See the
+class documentation for an usage example.
+
+From a command line/terminal prompt, you can issue the following command to view
+the text mode ri documentation:
+
+    ri Tree::TreeNode
+
+Documentation on the web is available at:
+
+http://rubytree.rubyforge.org/rdoc
+
+== EXAMPLE:
+
+The following code-snippet implements this tree structure:
+
+                 +------------+
+                 |    ROOT    |
+                 +-----+------+
+         +-------------+------------+
+         |                          |
+ +-------+-------+          +-------+-------+
+ |  CHILD 1      |          |  CHILD 2      |
+ +-------+-------+          +---------------+
+         |
+         |
+ +-------+-------+
+ | GRANDCHILD 1  |
+ +---------------+
+
+ require 'tree'
+
+ myTreeRoot = Tree::TreeNode.new("ROOT", "Root Content")
+
+ myTreeRoot << Tree::TreeNode.new("CHILD1", "Child1 Content") << Tree::TreeNode.new("GRANDCHILD1", "GrandChild1 Content")
+
+ myTreeRoot << Tree::TreeNode.new("CHILD2", "Child2 Content")
+
+ myTreeRoot.printTree
+
+ child1 = myTreeRoot["CHILD1"]
+
+ grandChild1 = myTreeRoot["CHILD1"]["GRANDCHILD1"]
+
+ siblingsOfChild1Array = child1.siblings
+
+ immediateChildrenArray = myTreeRoot.children
+
+ # Process all nodes
+
+ myTreeRoot.each { |node| node.content.reverse }
+
+ myTreeRoot.remove!(child1) # Remove the child
