+Redmine Wysiwyg Textile Editor
+=================
+
+A TinyMCE test application for Textile wiki pages.
+
+Currently this is a test version for in-house use only since there is a few issues that need to be sorted out regarding the conversion to and from textile and other security issues. If you stick to simple textile formatting it's not a problem, but when it comes to images and macros that's another issue.
+
+A better option would be to write a javascript wysiwyg editor for redmine like the one used in Trac. 
+
+Installation
+------------
+
+1. Copy the plugin directory into the vendor/plugins directory (make sure the name is redmine_wysiwyg_textile)
+2. Start Redmine
+3. Change text formatting (Administration > Settings > General > Text formatting) to "textile wysiwyg"
+
+Usage
+-----
+
+When editing a wiki page a radio button will be displayed below the Save button. This radio button allows the user to switch between the standard redmine textile editor and the tinymce wysiwyg editor.
