+Redmine Markdown Formatter
+==========================
+
+This is a redmine plugin for supporting Markdown as a wiki format.
+
+What is redmine?
+----------------
+
+Redmine is a flexible project management web application.
+See [the official site](http://www.redmine.org) for more details.
+
+
+What is Markdown?
+-----------------
+
+Markdown is a text-to-HTML conversion tool for web writers. Markdown allows
+you to write using an easy-to-read, easy-to-write plain text format, then
+convert it to structurally valid XHTML (or HTML).
+
+See [the article on John Gruber's blog](http://daringfireball.net/projects/markdown/)
+for more details.
+
+
+Plugin installation
+-------------------
+
+### Prerequisites
+
+* Redmine and its prerequisites
+*  [rdiscount](http://tomayko.com/writings/ruby-markdown-libraries-real-cheap-for-you-two-for-price-of-one) gem
+
+### Installation
+
+1. Copy the plugin directory into the vendor/plugins directory
+2. Start Redmine
+
+Installed plugins are listed on 'Admin -> Information' screen.
+
+Don't forget to change "Text formatting" option under
+Administration -> Settings -> General tab.
+
+### Credits
+* [Yuki Sonoda](http://github.com/yugui) did the real work by creating the
+  redmine_rd_formatter
+* Jean-Philippe Lang for making the change to Redmine (based on Yuki's patch) to
+  allow pluggable formatters
+
+### Future Plans
+* make the blockquote and unblockquote work for list items to indent
+  and un-indent.  Current behavior is kind of confusing.
