-Ruby API to Google Custom Search Engine (http://www.google.com/cse). Works with the paid version of CSE where you get results in XML format.
+This project is a Ruby API to Google's Custom Search Engine (http://www.google.com/cse).
 
+If you want a Google-like search engine for your web site, why not use Google? For $100/yr (more if you have over 1,000 pages) you can get access to Google search results for your site in XML format. The google_custom_search gem helps you access this web service and publish the results on your site however you like (all covered under Google's acceptable use policy).
 
+<b>Google Custom Search is currently compatible with Rails 2.x and Rails 3.</b>

   GOOGLE_SEARCH_CX = "..."
 
 You can find the CX value for your custom search engine via the search control panel on Google's site (click the "Get code" link and you'll see a hidden "cx" field in the sample HTML form).
 
+Optionally, you can set default Google search params, such as encoding, by setting up the <tt>GOOGLE_SEARCH_PARAMS</tt> hash in the same initializer:
+
+  GOOGLE_SEARCH_PARAMS = {
+    :ie => 'utf8',
+    :oe => 'utf8'

 If you're working outside of Rails you'll also need some +require+ statements:

 == Future
 
+* prevent NameError when GOOGLE_SEARCH_CX is missing: show nice msg
 * access to all data returned by Google
 * support for features of CSE free version
 * support for multiple CSEs in one app (GOOGLE_SEARCH_CX should be a hash)
