 GeoMereLaal
 ===========
+  GeoMereLaal plugin is all you need to create Location-Aware rails application based on   [W3C Geolocaton API](http://dev.w3.org/geo/api/spec-source.html "W3C draft for geolocation api"). 
+
+### What's Location-Awareness?
+   W3C proposed an API in which internet browsers can have capability to retrieve geo-location of the user via multiple sources (Wifi, LBS, IP, browser cookies) and share it with web apps so that apps can serve content based on user's location.    
 
-This plugin allows you to detect geo-loacation of your users through http://www.mozilla.com/en-US/firefox/geolocation/

+
+How do I use it?
+----------------
+### Step 1 : Install
+   <pre><code> script/plugin install git://github.com/parolkar/geo_mere_laal.git </code></pre> 
+### Step 2 : Create form (as you always did but with new helpers) 
+   Note: You may want to generate Address model this way script/generate model Address street:string locality:string city:string state:string country:string zip:string lat:string lng:string
+   <pre><code>   
+	<% form_tag('#') do  -%>
+	  <%= label :address,"street","Street" -%>
+	  <%= street_field :address, "street" %>    
+
+	  <%= label :address,"locality","Locality" -%>
+	  <%= locality_field :address, "locality" %>  
+
+	  <%= label :address,"city","City" -%>
+	  <%= city_field :address, "city" %>  
+
+  	  <%= label :address,"state","State" -%> 
+	  <%= state_field :address, "state" %>      
+
+ 	  <%= label :address,"country","Country Name" -%>
+	  <%= country_name_field :address, "country" %>
+
+      <%= label :address,"zip","Postal Code" -%>
+      <%= postal_code_field :address, "zip" %>
+
+	<% end %> 
+	</code></pre>
+### Step 3: ...... there is no step 3 ;-) 
+    The rendered form will auto fill the content with user's geolocation
