+Static Comment Generator for MovableType imported sites
+
+This plugin and template are a skeleton to generate a Jekyll static
+site with data exported from MovableType.
+
+The template is based on 
+[Matt Palmer's jekyll-static-comments](https://github.com/mpalmer/jekyll-static-comments).
+With the small hack added to MovableType Jeykll exporter, user can 
+export MovableType entries with comments.
+
+jekyll-import require 
+(a hack)[https://github.com/shigeya/jekyll-import/tree/mt_comment_hack]
+which (possibly) merged into jekyll-import.
+
+Generation Steps:
+
+- Export using jekyll/jekyll-import/mt.rb as directed. By adding
+  option `comments: true`, `_comments` directories are created and
+  all the comments are exported alongside with `_posts` directory.
+- Copy `mt_exported_static_comments.rb` to `_plugins` directory of
+  jekyll project directory
+- Copy `post.html` to `_layout` directory of  project directory
+- Build using Jekyll!
