+
+## Nanoc3
+
+### Minimal integration: just drop it in
+
+One simple route for lightweight integration is to simply install compass inside nanoc. Then edit config.rb to point to the stylesheets you want to use. This means you have to have the Compass watch command running in a separate window from the Nanoc compilation process. 
+
+Example project that works this way: http://github.com/unthinkingly/unthinkingly-blog
+
+### More formal integration
+
+At the top of the Nanoc Rules file, load the Compass configuration, like this:
+
+    require 'compass'
+
+    Compass.add_project_configuration 'compass/config.rb' # when using Compass 0.10
+    Compass.configuration.parse 'compass/config.rb'       # when using Compass < 0.10
+
+Your Compass configuration file (in compass/config.rb) could look like this (you may need to change the path to some directories depending on your directory structure):
+
+    http_path    = "/" 
+    project_path = "." 
+    css_dir      = "output/assets/style" 
+    sass_dir     = "content/assets/style" 
+    images_dir   = "output/assets/images"
+
+    # when using SCSS:
+    sass_options = {
+      :syntax => :scss
+    }
+
+
+To filter the stylesheets using Sass and Compass, call the sass filter with Sass engine options taken from Compass, like this:
+
+    filter :sass, Compass.sass_engine_options
+
+
+### Nanoc Projects using the formal approach
