 == Usage
 
   @users = User.all
 
-  #
-  # defaults are export headers and all fields
-  #
-
   @users.to_xls
   @users.to_xls(:headers => false)
   @users.to_xls(:columns => [:name, :role])
   @users.to_xls(:columns => [:name, {:company => [:name, :address]}])
   @users.to_xls(:columns => [:name, {:company => [:name, :address]}], :headers => [:name, :company, :address])
 
+In order to send a file from the controller, you can save it on your server first:
 
+  @users.to_xls.write '/path/to/file/users.xls'
+  send_file '/path/to/file/users.xls'
+
+Alternatively you can use the method to_xls_data and send_data
+
+  send_data @users.to_xls_data, :filename => 'users.xls'
+    
+The method to_xls_data accepts the same parameters as to_xls.
